“63. Adverting to the aspect of the exercise of jurisdiction by the High Courts under Section 482CrPC, in a case where the offence of defamation is claimed by the accused to have not been committed based on any of the Exceptions and a prayer for quashing is made, the law seems to be well settled that the High Courts can go no further and enlarge the scope of inquiry if the accused seeks to rely on materials which were not there before the Magistrate. This is based on the simple proposition that what the Magistrate could not do, the High Courts may not do. We may not be understood to undermine the High Courts' powers saved by Section 482CrPC; such powers are always available to be exercised ex debito justitiae i.e. to do real and substantial justice for the administration of which alone the High Courts exist. However, the tests laid down for quashing an FIR or criminal proceedings arising from a police report by the High Courts in the exercise of jurisdiction under Section 482CrPC not being substantially different from the tests laid down for quashing a process issued under Section 204 read with Section 200, the High Courts on recording due satisfaction are empowered to interfere if on a reading of the complaint, the substance of statements on oath of the complainant and the witness, if any, and documentary evidence as produced, no offence is made out and that proceedings, if allowed to continue, would amount to an abuse of the legal process. This too, would be impermissible if the justice of a given case does not overwhelmingly so demand.” (Emphasis supplied)
