Preponderance of Probability

Preponderance of Probability Latest News

The judgment on the title battle over the 1,500 square yards in the town of Ayodhya is founded on the “test of preponderance of probabilities” over who had possession of the outer and inner courtyards of the disputed premises, according to former Chief Justice of India D.Y. Chandrachud.

About Preponderance of Probability

  • It is a widely accepted standard of proof in civil proceedings.
  • The preponderance of probability refers to the greater likelihood of one event or fact over another. 
  • In this context, a fact is considered proven when the evidence suggests that the occurrence of the fact is more likely than not. 
  • It is not about certainty or eliminating all doubts but rather about weighing evidence to see which side presents a more probable scenario. 
  • In civil cases, the party bearing the burden of proof needs to show that their version of events is more plausible than the opposing party’s.
  • This standard contrasts sharply with the criminal law standard of “beyond a reasonable doubt,” where the prosecution must prove the defendant’s guilt to a much higher level of certainty. 
  • In civil cases, by contrast, the balance of probabilities leans toward the more convincing narrative.
  • In Narayan Ganesh Dastane v. Sucheta Narayan Dastane (1975), the Supreme Court of India stated that under Section 3 of the Indian Evidence Act, a fact is said to be proved when the court believes in its existence based on a “preponderance of probability.” 
  • The court applies this test by evaluating conflicting probabilities and choosing the most probable scenario.

Application of Preponderance of Probability in Civil Law

  • The preponderance of probability is the standard of proof used in most civil litigation. 
  • Civil cases typically involve disputes over rights, contracts, property, or torts, and the plaintiff must demonstrate that their claim is more likely true than false. 
  • For example, in a breach of contract case, the plaintiff must show that it is more likely than not that the contract was breached.

Hunga Tonga–Hunga Haʻapai (HTHH) Volcano

Hunga Tonga–Hunga Haʻapai (HTHH) Volcano

Hunga Tonga–Hunga Haʻapai Volcano Latest News

A collaborative research team recently returned from a major 54-day voyage on CSIRO research vessel (RV) Investigator to explore the impacts of the devastating 2022 eruption of Tonga's underwater Hunga Volcano.

About Hunga Tonga–Hunga Haʻapai Volcano

  • It is a submarine stratovolcano in the Tongan archipelago in the southern Pacific Ocean.
  • The HTHH volcano includes the small islands of Hunga Tonga and Hunga Ha’apai, along with shallow reefs along the caldera rim of a much larger submarine edifice in the western South Pacific Ocean, west of the main inhabited islands in the Kingdom of Tonga. 
  • It is located about 30 km south of the submarine volcano of Fonuafoʻou and 65 km north of Tongatapu, the country’s main island.
  • The volcano is part of the highly active Tonga–Kermadec Islands volcanic arc, a subduction zone extending from New Zealand north-northeast to Fiji.
    • The Tonga-Kermadec arc was formed as a result of the subduction of the Pacific Plate beneath the Indo-Australian Plate. 
  • It has erupted regularly over the past few decades.
  • On January 15, 2022, the HTHH volcano experienced an explosive eruption, considered one of the largest volcanic eruptions of the 21st century.
    • The eruption caused a plume of volcanic materials and gasses to be pushed into the stratosphere and sent shock waves through the atmosphere and tsunami waves across ocean basins.

What is a Stratovolcano?

  • It is a tall, steep, and cone-shaped type of volcano.
  • Unlike flat shield volcanoes, they have higher peaks.
  • They are typically found above subduction zones, and they are often part of large volcanically active regions, such as the Ring of Fire that frames much of the Pacific Ocean.
  • Strato Volcanoes comprise the largest percentage (~60%) of the Earth’s individual volcanoes, and most are characterized by eruptions of andesite and dacite, lavas that are cooler and more viscous than basalt.
  • These more viscous lavas allow gas pressures to build up to high levels. Therefore, these volcanoes often suffer explosive eruptions. 
  • They are usually about half-half lava and pyroclastic material, and the layering of these products gives them their other common name, composite volcanoes.
  • At their peak, they usually have a small crater. The crater may be filled with water or ice, or it may contain a volcanic dome during a period of relative inactivity.

Antlions

Antlions

Antlions Latest News

Researchers recently discovered two new species of antlions named Indophanes keralaensis and Indophanes sahyadriensis belonging to the family Myrmeleontidae under the order Neuroptera.

About Antlions

  • Antlions are a group of about 2,000 different species of insects. 
  • They belong to a family called Myrmeleontidae
  • They are named for the predatory nature of the larvae, which commonly trap ants and other small insects in pits dug into the ground.
  • Adult antlions are not as well known. They live for a shorter time than the larvae. 
    • Adult antlions, sometimes called antlion lacewings, usually fly at dusk or after dark. 
    • People sometimes mistake them for dragonflies or damselflies.
  • Habitat and Distribution:
    • Antlions live all over the world. 
    • Most types are found in warm, tropical places. 
    • But some species, like the European Euroleon nostras, live in colder areas. 
    • They often live in dry, sandy places. This is where their larvae can easily dig their traps. 
    • However, some larvae hide under leaves or other bits of nature. They wait to ambush their prey there.
  • They come in various shapes and sizes, with larvae typically measuring from a few millimeters to several centimeters, depending on the species. 
    • Antlion larvae have rounded bodies with long sickle-shaped jaws
    • The larvae are found at the base of cone-shaped pits in sandy areas.
    • In North America, these larvae are sometimes called doodlebugs. This is because of the wiggly marks they leave in the sand.
    • They usually remain in the larval stage for one to two years, depending on the species.
    • Once they pupate, they require up to one month to complete their development.
  • Antlions are harmless and cause no damage to flowers, people, or structures.
  • They are highly beneficial and feed on ants and other insects that fall into their traps.
