Article 61 allows either House of Parliament — Lok Sabha or Rajya Sabha — to initiate impeachment against the President. The charge requires at least one-fourth of total members to give notice, and must be passed by a two-thirds majority of total membership of the initiating House. The other House then investigates the charge. This is distinct from a no-confidence motion (which applies only to the PM/Council of Ministers in Lok Sabha).
