  • Surrogacy in India

    Age Cap for Surrogacy in India

    Why in the News?

    The Supreme Court of India has reserved its judgment (i.e. final decision is pending) in a set of petitions challenging the age-related eligibility criteria under the Surrogacy (Regulation) Act, 2021.

    These cases involve couples who had initiated the surrogacy process prior to the enactment of the law on January 25, 2022, but are now disqualified due to the new age limits.

    About the Surrogacy (Regulation) Act, 2021

    • Objective: To regulate surrogacy in India, prohibit commercial surrogacy, and promote ethical, altruistic surrogacy based on medical necessity.
    • Scope:

    Key Provisions:

    • Type Permitted: Only altruistic surrogacy (unpaid surrogate mother) is allowed; commercial surrogacy is banned.
    • Eligibility Criteria for Intending Couples:
      • Legally married for at least 5 years.
      • Woman must be 23–50 years of age; man must be 26–55 years.
      • Must not have any living biological, adopted, or surrogate child.
    • Eligibility for Single Women:
      • Only widows or divorcees between 35–45 years are eligible.
      • Unmarried women are not eligible (currently under challenge).
    • Surrogate Mother Criteria:
      • Must be a close relative, married, and have at least one biological child.
      • Age: 25–35 years.
    • Certification Requirement: A Certificate of Essentiality is required, including:
      • Proof of infertility
      • Court order for parentage and custody
      • Insurance for the surrogate mother
    • Penalties: Commercial surrogacy invites imprisonment (up to 10 years) and fines (up to ₹10 lakh).
    • Regulatory Structure:
      • National Surrogacy Board at the central level.
      • State Surrogacy Boards at the state level.

    Issues Highlighted by the Supreme Court:

    • No Transitional Provision: The Act lacks a grandfather clause to protect couples who began the surrogacy process (e.g., embryo freezing) before the law came into effect in January 2022.
    • Rigid Age Limits: The court questioned the fairness of disqualifying couples solely on age grounds, especially when natural pregnancies at older ages are not prohibited.
    • Violation of Fundamental Rights: Petitioners argued the age restrictions violate Article 14 (equality before law) and Article 21 (right to reproductive autonomy and personal liberty).
    • Exclusion of Unmarried Women: The law permits only widows or divorcees (35–45 years) to pursue surrogacy, which the court noted may be arbitrary and discriminatory.
    • Law’s Intent vs. Impact: The court stressed that while the law aims to prevent commercial surrogacy, it should not unreasonably prevent genuine intending parents from having children.

    Options: (a) fertilization of egg in vitro by the donor sperm (b) genetic modification of sperm producing cells (c) development of stem cells into functional embryos (d) prevention of mitochondrial diseases in offspring*

    Piprahwa Relics of Buddha

    Why in the News?

    The Union Culture Ministry has successfully retrieved the sacred ‘Piprahwa’ Buddhist relics, which were set to be auctioned in Hong Kong.

    Piprahwa Relics of Buddha

    About the Piprahwa Relics:

    • Discovery: Unearthed in 1898 by William Claxton Peppe, a British engineer, at Piprahwa (Siddharthnagar, Uttar Pradesh), near the Nepal border.

    • Historical Significance: Identified as ancient Kapilavastu, capital of the Shakya republic, where Prince Siddhartha (Buddha) lived before renunciation.

    • Findings at the Site: A buried stupa yielded a large stone coffer containing:

      • Bone fragments believed to be Buddha’s relics
      • Caskets made of soapstone and crystal
      • A sandstone coffer
      • Over 1,800 ornaments: pearls, rubies, sapphires, gold sheets
    • Legal Custody:

      • The British Crown claimed the relics under the Indian Treasure Trove Act, 1878.
      • Most artifacts were transferred to the Indian Museum, Kolkata.

    Stupas with Buddha’s Relics:

    • After the Buddha’s death (Mahaparinirvana), his cremated relics were divided among 8 kingdoms and a Brahmin named Drona, who coordinated their distribution.
    • Each recipient built a Stupa to enshrine their share of the relics, creating important pilgrimage sites and early centers of Buddhist worship.
    • The 9 stupas were located in Rajagriha, Vaishali, Kapilavastu, Allakappa, Ramagrama, Vethadipa, Pava, Kushinagar, and Pippalivana.
    • Emperor Ashoka (3rd century BCE) redistributed the relics from these stupas into thousands of new stupas across his empire.
    • The stupa at Ramagrama is unique because it is believed to remain untouched and still holds the original relics.
    • A typical early Buddhist stupa included a hemispherical mound (anda), a square railing (harmika), a central pillar (yashti) with umbrellas (chatra), and a path for circumambulation (pradakshinapatha).
    [UPSC 2023] With reference to ancient India, consider the following statements:

    Tsunami Waves triggered by quakes in Kamchatka Peninsula

    Why in the News?

    An 8.8 magnitude earthquake hit off Russia’s Kamchatka Peninsula, triggering 16-foot tsunamis that reached Hawaii and northern California in the US.

    About Earthquakes:

    • Overview: Sudden ground shaking caused by release of stored energy in Earth’s crust due to tectonic stress.
    • Cause: Occurs when tectonic plates slip at fault lines where stress had built up due to friction.
    • Seismic Waves: Energy travels as:
      • Primary Waves (P-waves): Fastest, compressional.
      • Secondary Waves (S-waves): Slower, shear motion.
    • Key Terms:
      • Focus (Hypocenter): Underground origin point.
      • Epicenter: Surface point directly above the focus.
    • Measurement:
      • Magnitude: Energy released (Richter Scale, logarithmic).
      • Intensity: Observed ground shaking (varies by location).
      • Seismograph: Records seismic wave activity.

    How Earthquakes Trigger Tsunamis?

    • Underwater Epicenter: Must occur beneath oceans to displace water.
    • Shallow Depth: Quakes at <70 km transfer energy more efficiently to water surface.
    • Reverse Faulting: One tectonic plate pushes over another, vertically shifting the seafloor.
    • Rapid Displacement: Sudden seafloor uplift/downthrust generates massive water waves.
    • High Magnitude: Quakes >7.0 (especially >8.0) likely to trigger tsunamis.

    About the Kamchatka Region:

    • Overview: Russian Far East; borders the North Pacific Ocean.
    • Tectonic Zone: Sits on the Kuril-Kamchatka Trench—Pacific Plate subducting under Okhotsk Plate at ~86 mm/year.
