Abeynayaka vs Senior Superintendent of Police – CA WRIT APPLICATION NO.674/2006-2014

In the case between Wilmot Abeynayaka, Senior Superintendent of Police (Petitioner), and the Inspector General of Police along with several senior police officials (Respondents), the court addressed whether the Inspector General of Police (IGP) could lawfully order a fresh inquiry into allegations that had already undergone investigation and resulted in the exoneration of the petitioner, particularly after the petitioner had retired. It was held that the initiation of a further inquiry, based on another anonymous petition and absent new evidence or statutory authority, constituted an abuse of process and violated principles of natural justice and administrative law. The decision reaffirmed the administrative law principle that an authority may not repeatedly adjudicate the same matter once
