The Law of Criminal Defamation Report

The 22nd Law Commission of India has submitted its Report No. 285 titled “The Law of Criminal Defamation” to the Government of India.

The Law Commission of India, a non-statutory body constituted by the Government of India. It was originally constituted in 1955 and is re-constituted from time to time. 22nd Law Commission tenure is up to August 2024.

Criminal Defamation in India

  • Defamation – It is the communication of a false statement that harms the reputation of an individual person, business, product, group, government, religion, or nation.
  • It is dealt by Section 499 & 500 of Indian Penal Code (IPC), 1860.
  • Section 499 - Defamation could be through words spoken or intended to be read, through signs about a person with the intention of damaging the reputation of that person.
  • Section 500 – It stipulates imprisonment of up to 2 years, with or without a fine, for someone held guilty of criminal defamation.
  • It was referred to the law panel by the law ministry in August, 2017.
  • Report – It stresses upon both the constitutional importance of defamation laws and their potential misuse.

In Subramanian Swamy v. Union of India, 2016, SC had upheld the constitutional validity of Section 499 of IPC, on account of it being a reasonable restriction under Article 19(2) to the freedom of speech and expression enshrined in Article 19(1) (a) of Indian Constitution.

  • Recommendation – Criminal defamation be retained within the scheme of criminal laws in the country.
  • Balance the right to freedom of speech and the right to reputation through the application of criminal defamation laws.
  • Right to freedom of speech and expression under Article 19(2) is subject to reasonable restrictions, like the right to reputation.
  • Right to reputation is derived from Article 21 that guarantees the right to life and personal liberty and so it has to be protected.

Bharatiya Nyaya Sanhita, 2023 has introduced community service as an alternative punishment, which has shown the most balanced approach in protecting one’s reputation and speech too.

Katabatic Winds

According to new research, glaciers around the world's tallest mountains are actually getting slightly colder during the warm season due to intensification of katabatic winds.

  • It is also called as mountain breeze as they move from a higher elevation of a mountain to a lower elevation.
  • OriginDuring and after sunset, air near the top of elevated land surfaces cools relatively quicker than air at lower altitudes.
  • As air cools, it becomes denser and heavier, then flows down the side of the mountain, resulting in a katabatic winds.

The ascending heated air during day is called as anabatic winds.

  • Over glacial mountains – If the slopes are covered with ice and snow, it will blow both at night and day.
  • On warm days, air just above the glacier's surface warms and rises, creates a vacuum.
  • Thus cold air around the snowy peaks rush down due to gravity, creating a downhill katabatic winds.

katabatic winds

  • Characteristics – It typically peak in the afternoon, reach speeds of over 100 mph.
  • ExamplesFoehn winds, Santa Ana and others
  • Climate change impacts – As average global temperatures rise worldwide, more air warms and rises from the mountain's surface, forcing more cold air down as katabatic winds, thus causing the cooling trend over the last 15 years over the Himalayas.
  • Impact on glacier melting – These chilly winds may have partly helped in slowing the melting of these glaciers which otherwise could have been even worse.
  • However, glaciers will continue to melt with climate change because glacial melting is not just linked to air temperature close to the ice.

Pyramid International Observatory is located on the southern face of Mount Everest along the Khumbu Valley.

Kariyachalli Island Restoration Project

T.N. pioneers a model for saving the sinking island of Kariyachalli in the Gulf of Mannar region.

  • Kariyachalli Island – It is located in Gulf of Mannar region in Tamil Nadu, 4th island from the Thoothukudi side.
  • Submergence – It used to be 16 hectares, but has shrunk to 5.97 hectares.

Studies have predicted that without intervention, Kariyachalli and Kasuwari Islands in Gulf of Mannar region will sink by 2035. Kasuwari Island is also proposed for restoration project.

  • Kariyachalli Island Restoration Project – A part of the Tamil Nadu Coastal Restoration Mission which had successfully brought back life of previously submerged Vaan Island.

Vaan Island is one of the 21 islands located about 6 km off Thoothukudi. It is a low-lying island with small-scale sand dunes, mostly reef sediments and has fringing type of coral reefs around it.

  • Tenure - 4 years from 2024-25 fiscal year.
  • Budget – Rs.50 crore, with World Bank assistance.

Gulf of Mannar

  • It is a set of 21 islands in total which includes estuaries, beaches and mudflats.
  • Location – It dot the southern coast of Tamil Nadu, between the holy town of Rameswaram and the Pearl City Thoothukudi.
  • Biodiversity – It is endowed with 3 distinct Coastal ecosystems namely coral reef, seagrass bed and mangroves.
  • It is India’s 1st marine biosphere reserve.
  • ThreatsCorals are mined for building materials and chemical industries which removed the hard substrates, exposing the shores of the islands to direct assault of wave action, leading to erosion.
  • So far, 2 islands have submerged, area of 15 of them has come down.


Jagdish S. Bakan, current Wildlife Warden of Gulf of Mannar Marine National Park has won the UNESCO Michel Batisse Award and the UNEP Asia Environmental Enforcement Award in 2023 for his work in the biosphere.

Future Circular Collider (FCC)       

CERN is pushing its plan to build the Future Circular Collider, a particle accelerator that will dwarf the Large Hadron Collider.

  • FCC – It is a particle accelerator that will be within a 91-kilometre ring of LHC.
  • Features – It will be 3 times bigger (and faster).
  • Budget – About 20 billion euros.
  • Development - It has not yet been approved by the member states yet as the feasibility study is due to be handed in at the end of 2025.
  • Even if it gets approved on time, it would only be operational by 2045 by the very earliest.

Large Hadron Collider

Future Circular Collider

A proton-proton machine.

An electron-positron collider.

1 stage machine

2 stage– Initially electron-positron, later to be proton-proton collider.



  • It is a European Organization for Nuclear Research.
  • Members23 member states.
  • Finance – Member states pay into the budget in proportion to their GDP, with Germany, the United Kingdom, France, and Italy being the biggest contributors.
  • It is home to Large Hadron Collider (LHC), largest machine in the world.
  • LHC – A particle accelerator, hosted inside a 27km long tunnel.
  • It accelerates protons and other subatomic particles to high speeds close to the speed of light and makes them collide with each other.
  • It was instrumental in the discovery of the Higgs Boson, so-called god particle in 2012.

Indian scientists have been involved in the design of many components of the LHC and played a significant role in various experiments like ALICE and CMS.
