(1) A Commission member can generally only be removed by the President, for misbehaviour, after the Supreme Court (on a presidential reference) inquires and reports that removal is warranted. (2) Pending that Supreme Court inquiry, the President/Governor may suspend the member. (3) The President may directly remove a member (without the Supreme Court process) if they're adjudged insolvent, take outside paid employment, or are, in the President's opinion, unfit due to mental/physical infirmity. (4) Having a personal stake or interest in a government contract counts as "misbehaviour" for these purposes.
This gives Public Service Commission members the same strong job-security protection pattern seen elsewhere for independent constitutional offices (like judges) - removal for genuine misconduct requires an independent Supreme Court inquiry first, insulating the Commission from being pressured or purged by the government of the day, with only narrow specific exceptions (insolvency, unauthorised outside employment, incapacity) allowing more direct removal.
If a government wanted to remove an inconvenient UPSC member for ordinary misconduct allegations, it cannot do so unilaterally - it must first refer the matter to the Supreme Court for an independent inquiry and adverse finding, protecting the Commission's independence from the executive.
