Davis Strait Proto-Microcontinent Latest News

A hidden landmass called the Davis Strait proto-microcontinent has been found beneath the icy waters of the Davis Strait, the body of water that separates Canada’s Baffin Island from Greenland.

About Davis Strait Proto-Microcontinent

  • It is a newly discovered submerged microcontinent located around the Davis Strait, a large stretch of water located between Canada’s Baffin Island and Greenland.
  • It has been named the Davis Strait proto-microcontinent since it formed owing to the tectonic evolution of the Davis Strait.
    • The strait was formed millions of years ago when the tectonic plates between the two islands shifted, reconfiguring the Earth’s crust.
    • This resulted in the formation of a thick continental crust in the ocean, which has now been declared a newly discovered primitive microcontinent.
  • The microcontinent is 19–24 km thick thinned continental crust and is surrounded by two narrow bands of thin (15–17 km) continental crust. 
  • This crust separates it from mainland Greenland and Baffin Island.

Key Facts about Davis Strait

  • It is a bay of the northern Atlantic Ocean, lying between southeastern Baffin Island (Canada) and southwestern Greenland.
  • The strait separates the depths of Baffin Bay (north) from those of the Labrador Sea (south) and forms part of the Northwest Passage, a route through the Canadian Arctic Archipelago linking the Atlantic and Arctic oceans. 
  • It is approximately 400 miles (650 km) north to south and 200 to 400 miles wide. 
  • It is one of the broadest straits in the world.
  • The Davis Strait is home to complex geological formations such as underwater basins and ridges that were created due to the strike-slip faulting along the Ungava Fault Zone around 45 to 62 million years ago. 
  • It triggered plate tectonic movements in the Labrador Sea and the Baffin Bay, leading to the formation of the Strait.

  • Criminalisation of Civil Disputes FAQ’s

Criminalisation of Civil Disputes Latest News

  • Chief Justice of India Sanjiv Khanna recently criticized the Uttar Pradesh government for the increasing practice of converting routine civil disputes into criminal cases. 
  • His remarks came during a hearing on an appeal by two individuals involved in a cheque bounce case, who were additionally charged with serious criminal offenses such as breach of trust, intimidation, and criminal conspiracy. 
  • The Chief Justice expressed concern over the misuse of criminal law to pressurize parties in civil matters.

CJI's Remarks on Converting Civil Disputes into Criminal Cases

  • Chief Justice of India Sanjiv Khanna expressed strong disapproval of the growing trend of converting civil disputes into criminal cases, particularly in Uttar Pradesh. 
  • The Chief Justice emphasized that disputes over civil issues should not be treated as crimes and warned of a breakdown of the rule of law in the state.

Misuse of Criminal Law in Civil Matters

  • The Chief Justice highlighted the concerning trend where civil cases—such as cheque bounce, money recovery, contractual disagreements, inheritance issues, property partitions, and commercial transactions—are increasingly being framed as criminal cases. 
  • This shift often aims to apply pressure on the opposing party, undermining the fairness of the legal process.

Modus Operandi of Converting Civil Disputes into Criminal Cases

  • A common tactic in these cases is to accuse the opposing party of dishonest intentions from the outset of a civil arrangement, such as a loan, contract, or agreement. 
  • For example, if Mr. A lends money to Mr. B, and Mr. B fails to repay, the matter typically falls under civil law. 
  • However, Mr. A may claim that Mr. B never intended to repay the loan and obtained the money through deceit.
  • This leads to criminal charges under Section 420 (cheating) of the Indian Penal Code, now included under Section 318 of the Bharatiya Nyaya Sanhita (BNS).

Reasons Behind the Shift to Criminal Cases

  • Legal experts suggest that many individuals perceive civil law as an ineffective remedy due to the prolonged nature of civil litigation. 
  • This is particularly evident in family disputes, where extended legal battles often result in the breakdown of marriages or family relationships. 
  • There is also a belief that criminal cases can prompt quicker settlements. In some instances, people with influence or by incentivizing police officials get FIRs registered to pressure the opposing party.

Growing Backlog in Civil and Criminal Cases

  • As per the National Judicial Data Grid, there are currently over 1.08 crore civil cases pending in District Courts across India, with more than 68% of these cases being older than one year. 
  • Additionally, out of the 4.52 crore total pending cases, 76% (3.44 crore) are criminal cases.

Courts' Stance on Civil vs. Criminal Disputes

  • The Supreme Court has consistently cautioned against the misuse of criminal law for matters that are essentially civil in nature. 
  • In January 2000, in the case of G. Sagar Suri vs. State of UP, the Court warned that criminal proceedings should not be used as a shortcut for civil remedies. 
  • It emphasized that criminal courts must exercise great caution before issuing processes, as criminal charges carry serious consequences for the accused.

Court's Observations in C. Subbiah @ Kadambur Jayaraj vs. The Superintendent of Police (May 2024)

  • The Supreme Court remarked, "It cannot be doubted that a dispute which is purely civil in nature has been given a colour of criminal prosecution alleging fraud and criminal breach of trust by misusing the tool of criminal law."
  • This highlights the growing concern over the misuse of criminal law in civil matters.

Way Forward: Court's Recommendations to Curb Abuse of Criminal Law

  • In the Indian Oil Corpn. vs. NEPC India Ltd. (2006) case, the SC emphasized that while individuals with legitimate grievances should have access to criminal law remedies.
  • However, those who initiate or continue criminal proceedings knowing they are unwarranted should be held accountable. 
  • The Court suggested that such complainants should face legal consequences after the criminal proceedings are found to be baseless and civil remedies should be pursued instead.

Practical Solution: Use of Section 250 Cr.P.C.

  • To prevent the misuse of criminal law, the Court recommended a practical solution: frequent use of Section 250 of the Criminal Procedure Code (Cr.P.C.)
    • Section 395 of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, deals with orders to pay compensation to victims of crimes.
  • This section allows courts to grant compensation to innocent parties who are subjected to unwarranted accusations. 
  • The Court proposed that judges should exercise this power more often when they discern malice, frivolousness, or ulterior motives behind criminal complaints. 
  • This would help deter unnecessary prosecutions and prevent harassment of innocent individuals.

Criminalisation of Civil Disputes FAQ’s

Q1. What is Criminalisation of civil disputes?

Ans. It refers to using criminal law to settle civil issues like loans, contracts, or inheritance through pressure or intimidation.

Q2. What did the Chief Justice say about civil disputes?

Ans. CJI criticized converting civil issues into criminal cases, calling it a threat to rule of law, especially in Uttar Pradesh.

Q3. Why are civil disputes turned into criminal cases?

Ans. Due to delayed civil trials, people misuse criminal charges to pressure opponents into quicker settlements or compromises.

Q4. What has the Supreme Court ruled on this misuse?

Ans. The Court warned against criminal courts being used as shortcuts for civil remedies and stressed cautious process issuance.

Q5. What is the court's recommended solution?

Ans. Frequent application of BNSS Section 395 (formerly CrPC 250) to penalize false complainants and prevent legal harassment.

Exoplanet Latest News

  • On April 17, an international research team published a paper in which it reported that the distant exoplanet K2-18b may be habitable.

Introduction

  • In a significant development in space science, an international research team has reported signs that exoplanet K2-18b, located 124 light-years away from Earth in the Leo constellation, may exhibit characteristics of a habitable world. 
  • The recent findings, based on data from the James Webb Space Telescope (JWST), suggest the presence of potential biomarkers in its atmosphere, sparking cautious optimism within the scientific community.

Understanding K2-18b and Its Discovery

  • K2-18b is a distant exoplanet discovered in 2015 by the Kepler telescope. It is about 5.2 times wider and nine times more massive than Earth. 
  • Orbiting its host star K2-18, the planet receives a comparable amount of stellar radiation as Earth receives from the Sun, making it a strong candidate for further habitability studies.
  • In 2019, NASA’s Hubble Space Telescope detected signs of water vapour in K2-18b’s atmosphere. 
  • Later, in 2023 and 2024, the James Webb Space Telescope provided stronger evidence of carbon dioxide and methane, essential components in the quest to find life-supporting planets.

Hycean World Hypothesis and Atmospheric Composition

  • Researchers theorize that K2-18b could be a Hycean world, a type of planet enveloped by a hydrogen-rich atmosphere and potentially hosting a liquid water ocean beneath. 
  • Computer simulations suggest that such worlds may possess moderate greenhouse conditions and even a stratosphere, despite their exotic environment.
  • The JWST has indicated the presence of carbon-based molecules like carbon oxides and even dimethyl sulphide (DMS) or dimethyl disulphide (DMDS). 
  • On Earth, DMS is primarily produced by marine phytoplankton, indicating that its presence in extra-terrestrial atmospheres could point to biological activity.

The Significance of Dimethyl Sulphide (DMS)

  • The detection of DMS or DMDS is considered the most exciting outcome of the K2-18b analysis. 
  • On Earth, DMS is almost exclusively of biological origin, released when oceanic phytoplankton decompose
  • It is also produced when bacteria break down plant matter. The detection of DMS in large quantities, up to 1,000 times higher than on Earth, suggests there may be an active production source on K2-18b's surface.
  • However, distinguishing between DMS and DMDS is complex due to their overlapping spectral signals
  • Moreover, the possibility of non-biological sources, such as volcanic eruptions or cometary chemistry, complicates direct interpretation.

Caution Against Premature Conclusions

  • Despite these intriguing findings, the scientific community urges caution. 
  • The JWST data have limitations, including detection thresholds and reliance on computer models that may not perfectly simulate unknown atmospheric dynamics.
  • There have been prior instances of premature claims in exoplanet studies. 
  • For instance, in 2024, researchers discovered that comet 67P/Churyumov-Gerasimenko contained DMS of abiotic origin, raising the possibility that DMS may not always be a biosignature.
  • Additionally, a U.S.-based study suggested K2-18b could be a "mini-Neptune" with a gas-rich envelope, not necessarily requiring biological processes to explain its chemical composition. 
  • Another reanalysis published in early 2025 challenged earlier findings, claiming there is no statistically significant evidence of carbon dioxide or DMS.

Challenges in Confirming Life on Exoplanets

  • Detecting potential life-supporting conditions from vast distances relies heavily on indirect evidence. 
  • These include signs of specific molecules, thermal conditions, and radiation levels. 
  • However, confirmation of extraterrestrial life would require direct detection, something that current technologies like JWST cannot provide conclusively.
  • Hence, while K2-18b remains a promising candidate, claims of it being habitable must be tempered with scientific rigour and scepticism.

Conclusion

  • K2-18b presents a compelling case for habitability, with its hydrogen-rich atmosphere, the presence of water vapour, and signs of carbon-based molecules. 
  • The potential detection of dimethyl sulphide lends further intrigue to this distant world. 
  • However, with conflicting studies and technological limitations, scientists continue to investigate the data with caution. 
  • K2-18b may or may not host life, but its study will undoubtedly enrich our understanding of planetary atmospheres and the parameters for life beyond Earth.
