Special Provisions
(1) If the President is satisfied India's (or part of its) financial stability/credit is threatened, the President may proclaim a Financial Emergency. (2) It can be revoked/varied, must be laid before Parliament, and lapses after 2 months unless approved by both Houses (with special Lok Sabha-dissolution rules) - once approved, it continues until revoked (no fixed further renewal cycle is specified in the text shown here). (3) During it, the Union can direct states on financial propriety and other necessary matters. (4) Such directions may include reducing salaries/allowances of state (or, for the President's own separate directions, Union) government personnel - including judges of the Supreme Court and High Courts - and requiring state Money Bills to be reserved for the President's consideration.
This is the least-used of India's three emergency types - a Financial Emergency has never actually been declared in India's history - but it would give the Union sweeping power over both Union and state government finances, including the extraordinary ability to reduce judges' salaries (normally constitutionally protected from reduction after appointment under Articles 125/221), reflecting just how severe a genuine national financial crisis under this article is meant to be.
Even though a Financial Emergency has never been declared, its provisions occasionally surface in public discussion during severe economic stress - what makes it notable is that even judges' salaries, which are otherwise constitutionally protected from being reduced after appointment, could be cut under a genuine Financial Emergency.
