Legislative privilege allows Parliament and state legislatures to punish members and outsiders for breach of privilege, including by ordering arrest or imprisonment. However, courts have consistently held that such powers do not operate in a constitutional vacuum. Article 21 guarantees personal liberty even against legislative action, and the Supreme Court has ruled that privilege cannot override fundamental rights. The tension between legislative autonomy under Articles 105 and 194 and justiciable constitutional rights remains a live constitutional question.

Legislative privileges under Articles 105 and 194 of the Constitution protect the functioning of Parliament and state legislatures. These provisions, modelled on the Westminster system, give legislatures the power to regulate their own proceedings, punish for contempt, and exclude outsiders. Crucially, until the privileges are codified by law, legislatures enjoy the privileges that the House of Commons possessed as of 1950.

The constitutional tension arises when a legislature exercises its privilege power to detain or punish an individual. Article 21 guarantees that no person shall be deprived of personal liberty except by procedure established by law. The Supreme Court in M.S.M. Sharma v. Shri Krishna Sinha (1958) held that legislative privilege could override freedom of speech under Article 19(1)(a) but left open the Art 21 question. The landmark case of Searchlight (1959) affirmed that courts have limited jurisdiction to examine privilege claims.

The pivotal shift came in Raja Ram Pal v. Hon'ble Speaker (2007), where a Constitution Bench held that courts can examine whether the exercise of privilege violates fundamental rights, particularly Articles 20 and 21. The court applied a proportionality-adjacent test: privilege exists to protect the dignity and functioning of the House, not to serve as an instrument of arbitrary detention. Article 300A, protecting property rights against state deprivation, adds a further layer where privilege actions involve seizure of property.

For CLAT PG, the examiner tests whether aspirants understand that privileges are not absolute, that Article 21 acts as an external constitutional check, and that judicial review — while restricted — is not entirely excluded from privilege matters.
