How have courts interpreted a procedural statute relating to jurisdiction where there has been no denial of due process?

That there should be applied such a liberal construction appears from the mandate of Government Code section 65801, which is that no action by any legislative or administrative body shall be set aside by any court as to any matter pertaining to appeals or any matters of procedure whatever, unless after consideration of the entire case, including the evidence, a different result would have been probable if the error had not occurred. Although this section would not confer jurisdiction where none existed, it does justify liberal interpretation of the procedural statute relating to jurisdiction, where there has been no denial of due process.
