UPSC CURRENT AFFAIRS – 21 JULY 2026

Context: A public debate emerged following recurring political realignments and defections across major regional parties like the Shiv Sena (UBT) and the Trinamool Congress.

About Defections Affect Moral Sanctity of Democracy:

What is defection?

• Defection refers to the act by an elected representative of abandoning allegiance to the political party on whose ticket or symbol they were elected to join another party or function independently. Popularly termed “Aaya Ram, Gaya Ram“ politics, defection transforms a solemn public mandate into a transactional asset traded for political office, power, or personal protection.

Constitutional Provisions and What Amounts to Defection:

Defection is governed by the Tenth Schedule of the Constitution of India, inserted via the 52nd Constitutional Amendment Act, 1985. The associated articles defining disqualification are:

• Article 102(2): Disqualification criteria for Members of Parliament (Lok Sabha and Rajya Sabha).
• Article 191(2): Disqualification criteria for Members of State Legislative Assemblies (MLAs) and Councils (MLCs).

A legislator incurs disqualification under the Tenth Schedule if:

1. They voluntarily give up membership of their political party (determined by explicit resignation or implied conduct).
2. They vote or abstain from voting in the House contrary to any direction (whip) issued by their political party without prior permission or post-facto condonation within 15 days.
3. An Independent elected member joins any political party after the election.
4. A Nominated member joins any political party after the expiry of six months from taking their seat.

Note: The 91st Constitutional Amendment Act, 2003 abolished the “one-third split” exception. Currently, protection from disqualification requires a merger involving at least two-thirds of the members of the legislature party.

Reasons for the Rise in Defections in India:

• The Pursuit of Power and Patronage: Political ideology has increasingly taken a backseat to pragmatism, with legislators defecting primarily to secure cabinet berths or administrative control.
• Weaponization of Investigative Agencies: Elected representatives facing corruption inquiries or legal challenges frequently defect to ruling parties to obtain political immunity and reduce investigative intensity.
• Partisan Role of the Speaker: Speakers often delay decisions on disqualification petitions indefinitely to allow ruling coalitions to survive floor tests, serving political rather than judicial interests.
• Exploitation of the Merger Loophole: Defecting groups bypass individual disqualifications by leveraging the two-thirds merger exemption under Paragraph 4 of the Tenth Schedule.
• Absence of Strict Internal Party Democracy: Monopolistic party command structures stifle internal dissent, prompting frustrated leaders to defect rather than challenge the leadership internally.

How Defection Breaks the Moral Sanctity of Democracy?

• Unilateral Betrayal of the Voter’s Contract: Citizens cast ballots based on a party’s manifesto, symbol, and ideology. Defecting after an election converts a collective public mandate into personal property.
• Erosion of the Institutional Opposition: Continuous migration of opposition legislators to ruling parties weakens parliamentary oversight, transforming elections into struggles for power rather than contests of ideas.
• Undermining Public Faith in Democratic Neutrality: Strategic realignments to escape legal probes erode public confidence that investigative and state institutions operate fairly.
• Normalizing Transactional “Marketplace” Governance: Defection reduces political office to a tradable asset—similar to historical “Transformismo”—where governments are held together by patronage rather than principle.
• Dispossessing the Voter: When elected officials switch parties, voters are left without genuine representation, reducing democratic choices to empty political theater.

Key Supreme Court Judgments on Anti-Defection:

• Kihoto Hollohan v. Zachillhu (1992): The Supreme Court upheld the constitutional validity of the Tenth Schedule, ruling that the Speaker acts as a quasi-judicial tribunal and their decisions are subject to judicial review by High Courts and the Supreme Court.
• Keisham Meghachandra Singh v. Speaker, Manipur (2020): The Court ruled that Speakers must decide disqualification petitions within a reasonable timeframe—setting a firm outer limit of three months—and recommended establishing an independent permanent tribunal for disqualifications.
• Subhash Desai v. Governor of Maharashtra (2023): The SC clarified that the defense of a “split” is no longer valid under the Tenth Schedule. It held that a Governor cannot call for a trust vote based purely on internal party dissent without objective evidence.
• Padi Kaushik Reddy Case (2025): Reaffirming the Keisham Meghachandra principle, the Apex Court directed the Telangana Speaker to decide pending MLA disqualification petitions within three months, stating that setting strict timelines is legally binding to prevent endless delays.

Way Forward:

• Transferring Adjudication to an Independent Tribunal: Shift the authority to decide defection cases from the Speaker to an independent body, such as a tribunal chaired by a retired judge or the Election Commission of India.
• Enforcing Enforceable Time-Bound Decisions: Amend the Tenth Schedule to mandate that all disqualification petitions must be resolved within a strict 60-to-90-day window.
• Mandatory Resignation and Bar on Public Office: Mandate that any defecting legislator automatically forfeit their seat and be barred from contesting elections or holding public office for the remainder of that legislative term.
• Restricting the Application of the Party Whip: Limit the enforcement of political party whips strictly to crucial votes, such as No-Confidence Motions, Money Bills, and Budget approvals, allowing internal debate on general legislation.
• Strengthening Electoral Accountability and Citizen Voice: Foster public awareness through civil society groups to hold defecting representatives accountable at the ballot box.

Conclusion:

While the Tenth Schedule introduced an initial framework to curb opportunistic party-switching, systemic loopholes and delays in adjudication have weakened its effectiveness. Protecting the sanctity of the democratic mandate requires transferring disqualification decisions to an independent body and enforcing strict timelines to ensure that political office serves the public good rather than personal ambition.

Context: Chennai-headquartered deep-tech startup The ePlane Company (incubated at IIT Madras) unveiled e200X (PT-01), India’s first full-scale prototype of an electric vertical take-off and landing (eVTOL) aircraft.

About India’s First eVTOL Aircraft (e200X):

What It Is?

• An electric vertical take-off and landing (eVTOL) aircraft—often termed an electric air taxi—is a zero-emission, battery-powered aircraft that lifts off and lands vertically like a helicopter before transitioning to forward winged flight like a conventional airplane.

Developed By: The e200X platform was engineered, designed, and assembled in-house by The ePlane Company.

How It Works?

• Vertical Lift vs. Forward Flight: Unlike complex tilt-rotor designs that physically rotate engines, the e200X uses separate, dedicated propulsion sets: six vertical lift rotors for hover/take-off and four forward propellers for cruise flight.
• Distributed Electric Propulsion (DEP): If any single motor or propeller fails during flight, the remaining motors automatically redistribute thrust to descend or land safely, eliminating single-point mechanical failures.
• Patented Synergistic Lift Architecture: Built with a patented wing design that provides aerodynamic lift at low airspeeds. This allows the aircraft to maintain stability without requiring an intrusive, wide wingspan.
• Advanced Edge Compute & Sensor Fusion: Driven by an 800V high-voltage EV powertrain, the aircraft runs on the NVIDIA IGX Thor platform, fusing real-time data from cameras, LiDAR, and radar to give the pilot a 360° view through congested urban environments.

Key Features of the e200X:

• Ultra-Compact Global Footprint: Measures just 8 meters × 11 meters. This footprint allows it to operate directly from existing helipads or standard hospital rooftops without requiring purpose-built vertiports.
• Carbon-Fiber Composite Structure: Constructed out of lightweight carbon-fiber composites with a maximum gross vehicle weight of 2 tonnes.
• Payload & Operating Range: Engineered to carry 1 pilot plus a 200 kg payload (fitting up to 2 passengers or a trauma patient with a paramedic) with a range of 110 km on a single charge.
• Digital Twin Validation: Developed and tested virtually using NVIDIA Omniverse before physical assembly, backed by over 10,000 km of flight testing on subscale demonstrators.

Key Applications:

• Enables rapid transport of critical patients, medical teams, and equipment while bypassing urban traffic.
• Supports fast airport transfers and urban logistics along fixed routes, reducing travel time significantly.

Context: For the first time in Indian cinema history, a Santhali-language film titled Angen (Invisible) won a National Film Award.

• Announced at the 72nd National Film Awards, director Ravi Raj Murmu received the prestigious honor for Best Debut Film of a Director in the Non-Feature Category.

About The National Award-Winning Film ‘Angen’:

What It Is?

• Angen is a 12-minute 10-second Santhali short film inspired by a mystical indigenous folktale passed down through generations. It marks a historic milestone as the first Santhali film ever to win a National Film Award, bringing Jharkhand’s rich tribal culture and storytelling to the national stage.

Directed By: The short film was written and directed by Ravi Raj Murmu, a 34-year-old filmmaker and Film and Television Institute of India (FTII), Pune graduate from Jaduguda in East Singhbhum, Jharkhand.

Core Theme and Plot:

• The Folklore Narrative: The plot centers on an innocent shepherd boy whose flute playing attracts a celestial deity (one of the seven sisters/goddesses). Mesmerized by his music, she uses her divine powers to take him to the heavenly realm. Overcome by memories of his roots, he embarks on a journey back to Earth, only to discover that his beloved village has completely vanished.
• Societal Allegory: The film uses the folktale as a metaphor for contemporary social issues—specifically the large-scale migration of young villagers to metropolitan cities in search of modern opportunities. It reflects on how blindly chasing development often disconnects youth from their native language, culture, and social identity.

Key Features of the Film:

• Non-Feature Short Format: Running at a tight 12 minutes and 10 seconds, the film was initially developed alongside students at Karim City College, Jamshedpur.
• Indigenous Music & Cast: Stars local performers Ramchandra Mardi, Saloni, Jeetray Hansda, and Phoolmani. The score features original Santhali folk compositions written by Santhali litterateur Durgaprasad Murmu and composed by Nunaram and Nishant Ram Teke.
• Philosophical Message: Emphasizes that while embracing modernity is necessary, remaining rooted in one’s land, language, and ancestral heritage is essential to preserving indigenous identity.

Significance:

• The National Award brings mainstream recognition to Santhali cinema, promoting tribal-language films and indigenous storytelling.
• The award encourages preservation of Santhali folklore and traditions through cinema while inspiring regional filmmakers.

Context: Delhi Police cracked down on a major demonstration by the Cockroach Janta Party (CJP) as thousands of protesters attempted to march toward the Parliament complex.

About The Right to Protest in India:

What It Is?

• The Right to Protest in India is a recognized democratic mechanism that allows citizens to assemble, express grievances, and challenge state policies. It is not an absolute right, but rather a constitutional freedom balanced against public order, safety, and the rights of the broader public.

Origin and Historical Context:

• The tradition of popular, non-violent marches (Satyagraha) served as a primary strategy during India’s struggle for independence.
• Post-independence, the framers of the Constitution embedded this right within the democratic framework to ensure that citizens retained a peaceful means to express dissent outside of periodic elections.

Constitutional Provisions:

• Article 19(1)(a): Guarantees the fundamental freedom of speech and expression.
• Article 19(1)(b): Guarantees the fundamental right to assemble peaceably and without arms.
• Article 19(2) & 19(3) [Reasonable Restrictions]: Authorizes the government to impose legal limits on protests in the interest of the sovereignty and integrity of India, state security, friendly relations with foreign states, public order, decency, morality, or to prevent contempt of court and incitement to offenses.

Key Supreme Court Judgments:

• Himat Lal K. Shah v. Commissioner of Police (1973): Right The Court ruled that freedom of assembly is essential to democracy. It drew a clear constitutional line between reasonable state regulation (like managing traffic) and arbitrary exclusion (outright bans).
• Mazdoor Kisan Shakti Sangathan v. Union of India (2018): Addressing repeated prohibitions around Parliament House, the SC mandated balanced guidelines. It established designated protest sites, set buffer zones around high-security buildings like Parliament and the Supreme Court, and banned weapons or lathis at demonstration sites.
• Amit Sahni v. Commissioner of Police (2020) [Shaheen Bagh Case]:  The SC ruled that protests cannot occupy public roads indefinitely or cause major inconvenience to the general public. Demonstrations must be restricted solely to designated areas.

Key Legal and Operational Features:

• Mandatory Police Permission: Organizers must obtain prior administrative and police clearance to hold demonstrations, allowing authorities to manage crowd size, traffic flow, and security.
• Designated Demonstration Sites: To protect public mobility, local administrations restrict high-density protests to designated grounds, such as Jantar Mantar and Ramlila Maidan in New Delhi, or Azad Maidan in Mumbai.
• Prohibitory Orders: Local authorities use statutory tools—such as Section 163 of the Bharatiya Nagarik Suraksha Sanhita (BNSS) to restrict unauthorized assemblies when there is an immediate threat to public order.

Context: Union Home Minister paid national tributes to the iconic Indian revolutionary freedom fighter Batukeshwar Dutt on his death anniversary.

About Batukeshwar Dutt:

Who He Was?

• Batukeshwar Dutt (also known as B.K. Dutt, Battu, or Mohan) was a prominent Indian socialist revolutionary. He is best known for executing the symbolic Central Legislative Assembly bombing in New Delhi alongside Bhagat Singh in 1929 to make the deaf hear against oppressive colonial legislation.

Early Days and Radicalization:

• Birth & Roots: Born on November 18, 1910, in Oari village, Purba Bardhaman district, West Bengal.
• Formative Years in Kanpur: He spent much of his youth and completed his schooling at P.P.N. High School in Kanpur, Uttar Pradesh.
• Meeting Bhagat Singh: In 1924, Dutt met Bhagat Singh in Kanpur. Under the mentorship of revolutionaries like Chandrashekhar Azad, he joined the revolutionary underground movement and mastered the art of bomb-making.

Key Contributions to the Freedom Movement:

• The Central Assembly Bombing (April 8, 1929):

• • Protest Against Colonial Bills: The British government introduced two anti-Indian measures—the Public Safety Bill and the Trade Disputes Bill—to suppress labor movements and revolutionaries.
  • The Action: On April 8, 1929, Dutt and Bhagat Singh entered the visitor’s gallery of the Central Assembly in Delhi. They threw two low-intensity, non-lethal bombs onto vacant areas of the floor, scattered anti-imperialist leaflets, and raised the historic slogan Inquilab Zindabad! (Long Live the Revolution!).
  • Voluntary Arrest: Refusing to flee, they courted arrest to use the British courtrooms as a public platform to spread their revolutionary message across India.

• Historic Hunger Strike for Political Prisoners: Following their arrest and sentence of life imprisonment, Dutt and Bhagat Singh launched an unprecedented hunger strike in jail. They protested against the abusive treatment of Indian prisoners compared to European inmates, ultimately forcing the British administration to grant fundamental rights and improved standards for political prisoners.
• Sentence and Cellular Jail Hardships: Sentenced to transportation for life (Kalapani) in 1929, Dutt was deported to the Cellular Jail in the Andaman Islands. He endured years of brutal forced labor and participated in major prison hunger strikes in 1933 and 1937.
• Quit India Movement (1942): After contracting tuberculosis in jail, he was released in 1938. Unwavering in his commitment, he joined Mahatma Gandhi’s Quit India Movement in 1942 and was imprisoned for another four years in Motihari Jail, Bihar.

Revolutionary Associations:

• Hindustan Socialist Republican Association (HSRA): A core member of this party, working alongside Bhagat Singh, Chandrashekhar Azad, and Sukhdev.
• Naujawan Bharat Sabha: Active in the youth wing formed to mobilize workers and students against colonial rule.

Last Days and Passing:

• Post-Independence Hardships: After 1947, Batukeshwar Dutt lived quietly in Patna, Bihar, with his family. Despite his sacrifices, he faced severe economic hardship and public neglect.
• Final Illness and Passing: In the 1960s, he developed bone cancer. He was brought to AIIMS Delhi for treatment, where he passed away on July 20, 1965, at the age of 54.
• Last Wish fulfilled: In accordance with his final request, he was cremated at Hussainiwala (Firozpur, Punjab), right beside his comrades Bhagat Singh, Rajguru, and Sukhdev.

Context: Union Home Minister Amit Shah is set to introduce The Prevention of Insults to National Honour (Amendment) Bill, 2026 in the Rajya Sabha.

About The Prevention of Insults to National Honour (Amendment) Bill, 2026:

What It Is?

• The proposed legislation is an amendment to the parent Prevention of Insults to National Honour Act, 1971, which criminalizes disrespect toward national symbols such as the National Flag, the Constitution, and the National Anthem. The 2026 Bill explicitly expands the scope of the 1971 Act to include the National Song (Vande Mataram).

Aim: The central objective of the Bill is to plug a long-standing statutory gap in the 1971 Act, which lacked specific penal provisions to protect the national song.

• By adding legal protections, the government aims to fulfill the vision articulated by Constituent Assembly President Dr. Rajendra Prasad on January 24, 1950, that Vande Mataram “shall be honoured equally with Jana Gana Mana and shall have equal status with it.”

Key Features of the Bill:

• Substitution of Section 3: Replaces Section 3 of the 1971 Act to place the National Song and National Anthem under the exact same protective legal umbrella.
• Criminalization of Interference: Explicitly makes it a criminal offense for anyone who intentionally:
  1. Prevents the singing of the National Anthem or the National Song, or
  2. Causes disturbance to any assembly or gathering engaged in such singing.
• Penalties: Establishes strict criminal sanctions for violators, including imprisonment for a term extending up to three years, a monetary fine, or both.
• Historical Reference: The Bill explicitly cites Bankim Chandra Chatterjee’s 1875 composition (later published in Anandamath in 1882) and its historical role in inspiring generations during India’s freedom struggle.

Significance:

• Grants Vande Mataram explicit legal protection, placing it on par with the National Anthem under the Prevention of Insults to National Honour Act.
• Rekindles debate over balancing national honour with Article 19 freedoms, as critics question whether legal compulsion undermines voluntary patriotism.

Context: Bihar Chief Minister inaugurated the 68.80 km Belwa-Minapur Link Channel (Belwadhar) in Sheohar, constructed at a cost of ₹130.88 crore.

About The Belwa-Minapur Link Channel:

What It Is?

• The Belwa-Minapur Link Channel is an artificial, high-capacity water diversion It functions as the foundational phase of the broader Bagmati-Budhi Gandak River Interlinking Project and the Bagmati Flood Management Project, creating a regulated hydraulic bridge between two major river basins in Bihar.
