About Red Fort

  • The Red Fort, or Lal Qila, is a Mughal fort located in Delhi, India.
  • Formerly known as Quila-e-Mubarak, or the Blessed Fort, the Red Fort lies along the banks of the river Yamuna, whose waters fed the moats surrounding the fort. 
  • It was built as the palace fort of Shahjahanabad – the new capital of the fifth Mughal Emperor of India, Shah Jahan.
  • Shah Jahan constructed it in 1639. It was designed by architects Ustad Ahmad Lahauri and Ustad Hamid.
  • Named for its massive enclosing walls of red sandstone, it is adjacent to an older fort, the Salimgarh, built by Islam Shah Suri in 1546, with which it forms the Red Fort Complex.
  • The fort complex served as the residence of Mughal Emperors for nearly 200 years, until 1857.
  • The fort was designated a UNESCO World Heritage site in 2007.
  • From the fort each year on Independence Day (August 15), the Indian prime minister participates in a flag-raising ceremony and delivers a televised address to the country.

Red Fort Architecture

  • The Red Fort’s massive red sandstone walls, which stand 75 feet (23 metres) high, enclose a complex of palaces and entertainment halls, projecting balconies, baths and indoor canals, and geometrical gardens, as well as an ornate mosque.
  • The planning of the palace is based on Islamic prototypes, but each pavilion reveals architectural elements typical of Mughal buildings, reflecting a fusion of Persian, Timurid, and Hindu traditions.
  • The fort is octagonal, with the north-south axis longer than the east-west axis.
  • Among the most famous structures of the complex are the Hall of Public Audience (Diwan-i-ʿAm), which has 60 red sandstone pillars supporting a flat roof, and the Hall of Private Audience (Diwan-i-Khas), which is smaller and has a pavilion of white marble.
  • The marble, floral decorations, and double domes in the fort's buildings exemplify later Mughal architecture.
  • It has 2 principal gates–Lahore Drawaza and Delhi Darwaza along its western and southern sides, respectively.

Doctrine of Escheat

Doctrine of Escheat

Doctrine of Escheat Latest News

The Supreme Court recently held that a State Government cannot invoke the doctrine of escheat under Section 29 of the Hindu Succession Act once a Hindu male has executed a Will, which has been declared to be valid and has been granted probate by a Court.

About Doctrine of Escheat

  • It is a significant legal concept that ensures no property is left without ownership, reverting it to the state if the original owner dies without legal heirs or fails to make a will. 
  • This legal process addresses the handling of unclaimed assets, protecting societal interests and maintaining order within the legal framework.
  • The doctrine addresses two primary situations: 
    • when a person dies intestate (without a will) and without heirs, and 
    • when property remains unclaimed or abandoned for a specific period.
  • The underlying principle of escheat is that property must always have an identifiable owner, and in the absence of heirs, the government assumes ownership. 
  • In modern legal systems, escheat serves as a way to maintain orderly succession and prevent assets from being wasted or misused.

Historical Origins of Escheat

  • Escheat originates from the Old French word “eschete,” meaning “to fall to”.
  • The concept of escheat is rooted in the feudal system of medieval Europe, where land was held by tenants under a lord.
  • If the tenant died without an heir or was convicted of certain crimes like treason, the land would escheat, or revert, to the lord. 
  • This system allowed for continuous control of land, ensuring that property remained within the hierarchy of the feudal structure. 
  • Over time, this evolved to include the monarch or the state as the ultimate recipient of property without heirs.

Escheat in Modern Legal Systems

  • In modern legal systems, escheat ensures that unclaimed or ownerless property does not remain in limbo but is transferred to the state. 
  • The state assumes ownership of such property, either permanently or temporarily, until rightful claimants can be found. 
  • Escheat laws vary across jurisdictions, with some countries having well-defined processes for handling unclaimed assets.
  • In India, escheat is regulated primarily through Section 29 of the Hindu Succession Act, 1956, and Article 296 of the Constitution. 
    • These provisions outline the circumstances under which property escheats to the state, safeguarding against unclaimed or abandoned property.
    • However, the Supreme Court made it clear that the doctrine of escheat under Section 29 of the Hindu Succession Act, 1956, is a remedy of last resort; it comes into play only when a person dies intestate and without any legal heirs.
    • Where a valid will is executed and duly probated, the property must devolve strictly in line with the testator’s intent, leaving no room for the State to assert rights over the estate.

Q4: Is the doctrine of escheat regulated in India?

Ans: In India, escheat is regulated primarily through Section 29 of the Hindu Succession Act, 1956, and Article 296 of the Constitution.
