Criminal Procedure Code , 1973 (2 of 1974), Section 406 - Transfer of criminal case - Convenience or inconvenience are inconsequential so far as the mandate of law is concerned.
"46. Jurisdiction of a court to conduct criminal prosecution is based on the provisions of the Code of Criminal Procedure. Often either the complainant or the accused have to travel across an entire State to attend to criminal proceedings before a jurisdictional court. In some cases to reach the venue of the trial court, a complainant or an accused may have to travel across several States. Likewise, witnesses too may also have to travel long distances in order to depose before the jurisdictional court.
If the plea of inconvenience for transferring the cases from one court to another, on the basis of time taken to travel to the court conducting the criminal trial is accepted, the provisions contained in the Criminal procedure Code earmarking the courts having jurisdiction to try cases would be rendered meaningless. Convenience or inconvenience are inconsequential so far as the mandate of law is concerned. The instant plea, therefore, deserves outright rejection."
