Inquiry into a Member's alleged misbehavior or incapacity requires a nominated judge, medical examination, and representation rights. Inquiry is initiated when the President refers reasonable grounds to the Chief Justice for nomination of a Supreme Court Judge, who is appointed by presidential order and given the articles of charge, imputations, witness statements and material documents; the Judge must complete the inquiry within specified time and allow the Member a written statement of defence. Alleged physical or mental incapacity may be investigated by a Presidential Medical Board whose report informs fitness to continue, and refusal to undergo examination permits a presumption of incapacity; charges may be amended with opportunity for fresh defence, and the Central Government appoints an officer or advocate to present the case while the Member may engage counsel.
