Red-Eared Slider Turtle

The Red-Eared Slider Turtle has recently been found accidently from the Malankara dam in Idukki.

  • It is a native of the southern U.S. (Mississippi river) and northern Mexico.
  • They live in still and warm waterbodies such as ponds, lakes, streams, and slow- running rivers.
  • Though they can be easily trapped in small waterbodies, it is not the case in larger waterbodies such as reservoirs.
  • It is identified as exotic and enlisted in the 100 most invasive species in the world.
  • They are considered a major threat to native turtle specials, as they mature fast, grow larger, and produce more offspring, and are very aggressive.
  • It can grow up to about 33 cm long, with a life span of close to 30 years.
  • It is also known to be a carrier of human-infected bacteria such as salmonella.
  • EU and Australia have imposed strict regulations on its trading and import.
  • It was first observed in private aquariums in the State of Kerala.

Appointment of Supreme Court Judges

9 judges of the Supreme Court including one third women have taken the oath, the biggest ever number at one go. It takes the total SC strength to 33, of whom 4 are women.

  • Articles 124(2) and 217 of the Constitution govern the appointment of judges to the Supreme Court (SC) and High Courts (HC) respectively.
  • Under this, the President has the power to make the appointment after “consultation” with such judges of SC and HC as the president may deem necessary.
  • The word “consultation” has been at the centre of the tussle between the executive and the judiciary power over judges’ appointment.
  • Its meaning has been evolved over the period of time by various SC judgments.
  • Its interpretation began in 1973 following the Indira Gandhi-led government’s move to supersede 3 senior judges and appoint Justice A N Ray as the Chief Justice of India (CJI).
  • First Judges Case (1981) - In “S P Gupta v Union of India”, the SC ruled that the President does not require the “concurrence” of the CJI in appointment of judges.
  • It however affirmed the pre-eminence of the executive in making appointments.
  • Second Judges Case (1993) - In Advocates-on-Record Association v Union of India, a 9-judge constitution bench evolved the ‘collegium system’ for appointment and transfer of judges in the higher judiciary.
  • Third Judges Case (1998) - President K R Narayanan issued a Presidential Reference to the SC over the meaning of the term “consultation”.
  • The ruling on this established a quorum and majority vote in the collegium to make recommendations to the President
  • Overall, all these 3 cases shrank the executive say in proposing a candidate for judgeship and also took away the executive’s veto power.
  • National Judicial Appointments Commission (NJAC) – In 2014, the government attempted to gain control on judicial appointments through constitutional amendments, but SC struck it down as unconstitutional.
  • HC Judges Appointment – It is initiated by the HC collegiums and then moves to the state government, the central government and then to the SC collegiums.
  • Number of Judges - In 1950, when it was established, it had 8 judges including the CJI.
  • Parliament has the power to increase the number of judges.
  • It gradually increased the number by from 8 to 34 in 2019 by amending the Supreme Court (Number of Judges) Act.
  • Vacancy – The SC continues to have one vacancy whereas the HCs on average have over a 30% vacancy.
  • Retirement - The age of retirement is 65 years for SC judges and 62 for HC judges.

In US, the Supreme Court judges serve for life.

  • Representation of Women - In 1989, Justice Fathima Beevi became the first judge to be appointed to the Supreme Court.
  • Since then, however, the SC has had only 11 women judges, inducing the three women appointed recently.
  • Before the recent appointment, Justice Indira Banerjee was the only woman judge in the Supreme Court.
  • Justice B V Nagarathna is in line to become India’s first woman CJI —80 years after Independence.

Mu Variant

WHO has classified yet another SARS-CoV-2 variant “B.1.621” as a variant of interest (VOI) and given it the label “Mu”.

  • The variant was first identified in Colombia in January, 2021.
  • Spread - The global prevalence of the Mu variant among sequenced cases has declined and is currently below 0.1%.
  • However, prevalence in Colombia (39%) and Ecuador (13%) has consistently increased.
  • Larger outbreaks were reported from countries in South America and Europe.
  • Cases have also been reported in the UK, US and Hong Kong.
  • It was added to Public Health England’s list of variants under investigation.

Classes of SARS-CoV-2 variants

  • Variant of Interest - A variant with specific genetic markers that have been associated with changes to receptor binding which affect its diagnosis and are expected to cause unique outbreak clusters.
  • It is known for it predicted increase in transmissibility.
  • It is classified based on factors such as genetic changes that are predicted or known to affect virus characteristics such as transmissibility, disease severity, immune escape etc.
  • It represents a lower level of concern than a variant of concern (VOC).
  • Variant of Concern - A variant for which there is evidence of an increase in transmissibility, more severe disease (e.g., increased hospitalizations or deaths).
  • It is known for its significant reduction in neutralization by antibodies generated during previous infection or vaccination, reduced effectiveness of treatments or vaccines, or diagnostic detection failures.
  • Example – Alpha, Beta and Delta variants of SARS-CoV-2.
  • Variant of High Consequence – It has clear evidence that prevention measures or medical countermeasures (MCMs) have significantly reduced effectiveness relative to previously circulating variants.
