  "summary": "Sikkim (སུ་ཁྱིམ་ in Tibetan / Indrakil / Sikkimese: 'New Palace') is a South Asian Himalayan mixed common-law/Sikkim-customary-law constituent state of the Indian Republic — structurally distinctive globally as the only modern post-WWII state-to-Indian-state-integration framework (Sikkim was an independent Buddhist-Hindu Himalayan monarchy 1642-1975, became an Indian protectorate 1950, and was integrated into India as the 22nd state via the Constitution (Thirty-Sixth Amendment) Act 1975 effective 26 April 1975 following a 14 April 1975 referendum in which 97% of voters supported abolishing the monarchy and joining India — contested by external observers but recognised by India), as the only Indian state operating constitutional Article 371-F special-status framework providing for the protection of Sikkim's pre-1975 laws and the Sikkim Subject Regulation 1961 ethnic-origin framework, and as the central jurisdiction of the largest Indian-state-level Buddhist-cultural-protection framework operating within a Hindu-majority Indian Federal framework. Sikkim comprises ~7,096 km² with a population of ~700,000, making it the second-smallest Indian state (after Goa) and least-populous. Family-law framework operates under a dual federal Indian common-law + Sikkim-customary-law framework including pre-1975 Sikkim Subject Regulation 1961 and Sikkim Old Laws preserved by Article 371-F. Parental authority and child custody operate under the Indian Hindu Marriage Act 1955, Muslim Personal Law (Shariat) Application Act 1937, and Sikkim-specific Old Laws applicable to Sikkimese persons of Bhutia, Lepcha, and Nepali heritage. The High Court of Sikkim (one of only two Indian High Courts established post-1975, with the Gauhati High Court) is the apex domestic appellate court; final appellate jurisdiction lies with the Supreme Court of India. Sikkim is silent on 'parental alienation' as a statutory label. India is a Hague Convention 1980 signatory but not a party (signed 2007, never ratified) — Sikkim is governed by the Indian non-ratification status.",
