Doctrine of Severability

Doctrine of Severability

Doctrine of Severability Latest News

The Supreme Court clarified that the Doctrine of Severability is applicable in Suits for Specific Performance, but only in exceptional cases.

About Doctrine of Severability

  • It is a fundamental legal principle that plays a crucial role in addressing the constitutionality of laws when some provisions are inconsistent with the Fundamental Rights guaranteed by the Constitution. 
  • In such cases, only the conflicting or repugnant part of the law will be considered void by the courts, not the entire statute. 
  • In simpler terms, if a specific part of a law violates the Constitution but can be separated from the rest of the law without affecting its functionality, only that problematic part will be removed, not the entire law.
  • Another aspect of the doctrine of severability is that if a law combines good and bad provisions using words like ‘and’ or ‘or,’ and the enforcement of the good provision does not depend on the bad one, they are considered severable. 
  • The good provision will be upheld and enforced even if the bad one cannot or does not exist. 
  • On the other hand, if there’s a provision that can be used for both legal and illegal purposes, it is invalid and cannot be allowed even for legal purposes.
  • The court will declare the entire Act as void if the valid and invalid portions are so intertwined that they cannot be separated. 
  • It is also called the doctrine of separability.

Landmark Cases on Doctrine of Severability

  • A.K Gopalan vs State of Madras: The court held that if the preventive detention provision (section 14) was removed, the rest of the Act would remain valid and effective. The violative part was separable from the valid part.
  • Minerva Mills vs Union of India: The court struck down section 4 of 55 of the 42nd Amendment Act, 1976, as it exceeded the amending power of Parliament. However, the remaining provisions of the Act were upheld and considered valid.
  • Kihoto Hollohan vs Zachillhu: The court declared paragraph 7 of the Tenth Schedule (inserted by the 52nd Amendment Act of 1985) unconstitutional. However, the rest of the Tenth Schedule, excluding paragraph 7, was upheld and considered constitutional.

Alfvén Waves

Alfvén Waves

Alfvén Waves Latest News

Researchers have made a major advance in solar physics by capturing the first direct evidence of small-scale torsional Alfvén waves in the Sun’s outer atmosphere, known as the corona.

About Alfvén Waves

  • Alfven waves are low-frequency, transverse electromagnetic waves that propagate along the Sun’s magnetic field lines.
  • It occurs in a plasma (or conducting fluid), resulting from the interaction of the magnetic fields and electric currents within it.
    • These waves were first proposed in 1942 by Nobel Prize-winning physicist Hannes Alfvén, are magnetic fluctuations that transfer energy through plasma.
  • Larger and more sporadic Alfven waves linked to solar flares have been detected before.
  • What Researchers have found?
    • The breakthrough was made possible by the unique capabilities of the Daniel K. Inouye Solar Telescope’s Cryogenic Near Infrared Spectropolarimeter (Cryo-NIRSP).
    • This is the first time the subtle, ever-present twisting waves, thought to be powerful enough to heat the corona, have been directly confirmed.
    • The study suggests that Alfven waves may account for at least half of the energy needed to heat the corona.

Leprosy

What is Leprosy?

Leprosy Latest News

Recently, the Maharashtra government has officially declared leprosy a “notifiable disease.”

About Leprosy

  • Leprosy is an infectious disease caused by a type of bacteria called Mycobacterium leprae.
  • It is also known as Hansen’s disease.
  • It primarily affects the skin, peripheral nerves, eyes and other organs.
  • It is a neglected tropical disease (NTD) which still occurs in more than 120 countries, with around 200 000 new cases reported every year. 
  • It was declared notifiable in 2005 uniformly under the National Leprosy Eradication Programme (NLEP), Union Ministry of Health and Family Welfare.

Transmission of Leprosy

  • The disease is transmitted through droplets from the nose and mouth of an untreated case of leprosy, containing the causative agent, following prolonged, close contact. 
  • The disease does not spread through casual contact (like shaking hands or hugging, sharing meals or sitting next to each other). 
  • The patient stops transmitting the disease upon initiation of treatment.

Symptoms of Leprosy

  • It usually takes about 3 to 5 years for symptoms to appear after you come into contact with the bacteria that cause leprosy.
  • The main symptom of leprosy is disfiguring skin sores, lumps, or bumps that don’t go away after several weeks or months.
  • In some cases, body parts may lose their sense of touch and pain, increasing the likelihood of injuries such as cuts and burns.

Treatment of Leprosy

  • Leprosy is a curable disease. 
  • The currently recommended treatment regimen consists of three medicines (dapsone, rifampicin and clofazimine) and is referred to as multi-drug therapy (MDT).

Stabilimenta

Stabilimenta

Stabilimenta Latest News

A new study has revealed that the mysterious silk decorations in some spider webs known as stabilimenta may be sophisticated tuning devices that enhance the spider’s ability to locate its next meal by controlling how vibrations travel through the web.

About Stabilimenta

  • Stabilimenta are highly UV-reflective distinctive silk structures found in multiple spider species’ webs. 
  • These “decorations” may look like zig-zagging threads spanning the gap between two adjacent “spokes,” or threads arranged in a circular “platform” around the web center.
  • The purpose of stabilimenta within the web is unclear
    • They could help collect water, regulate a spider’s body temperature, or even deter predatory wasps or birds to help the arachnids collect more insects. 
    • They also may help the spiders pinpoint where their prey is located by helping vibrations move throughout the web.
  • Not all spiders use stabilimenta, and members of the same species may decorate their webs in different ways.
