Formal rules of evidence or procedure which must be followed in a court of law shall not apply to the consideration of a proposed development agreement. No action, inaction or recommendation regarding a development agreement shall be held void or invalid on the ground of the improper admission or rejection of evidence or by reason of any error or informality, as to any matter procedure whatsoever unless, after an examination of the entire case, including the evidence, a court of law finds that the error complained of was prejudicial and that by reason of the error the complaining party sustained and suffered substantial injury, and that a different result would have been probable if the error had not occurred or existed. There is no presumption that error is prejudicial or that injury resulted if error is shown. (Ord. 2073 § 1, 1989)
