The Contempt of Courts Act, 1971
11. Power of High Court to try offences committed or offenders found Outside jurisdiction
A High Court shall have jurisdiction to inquire into or try a contempt of itself or of any court subordinate to it, whether the contempt is alleged to have been committed within or outside the local limits of its jurisdiction , and whether the person alleged to be guilty of contempt is within or outside such limits.
This section expands the ambit of the authority beyond what was till then considered to be possible but it does not confer a new jurisdiction. It merely widens the scope of our existing jurisdiction of a very special kind; State of Uttar Pradesh v. Radhey Shyam, 1983 Cr LJ 1153 (1162).
