Concept: The Constitution assigns each high constitutional functionary a distinct role and set of privileges. Among the Union's constitutional law officers, one specific provision grants a standing right to appear and be heard before every court in the country while carrying out official duties — this right is not a general feature of high constitutional office, but a privilege tied to a particular post.

Application: Article 76 of the Constitution establishes the office of the Attorney-General for India as the Union Government's chief law officer. Article 76(3) expressly provides that, in the performance of his duties, the Attorney-General shall have the right of audience in all courts in the territory of India.

Contrast: comparing each office against this specific constitutional privilege:

• Comptroller and Auditor General of India — established under Article 148 to audit the accounts of the Union and the States; its function is financial audit and reporting, not appearing before courts.

• Speaker of the House of the People — holds office under Article 93 to preside over Lok Sabha proceedings and rule on procedural matters; this office carries no court-audience privilege.

• Attorney-General of India — the post created by Article 76, whose holder is expressly given the audience right under Article 76(3) while discharging official duties.

• Prime Minister of India — heads the Union Council of Ministers under Article 75 to aid and advise the President in the exercise of executive functions; this executive role does not carry a judicial-audience privilege.

Cross-check: Article 76(3)'s plain text ties this specific audience right to the Attorney-General's office alone, consistent with the office's function as the government's advocate before the Supreme Court, High Courts, and other courts — no other constitutional office listed carries this privilege.
