In any prosecution or proceeding alleging a muni-meter parking violation, it shall be an affirmative defense to such violation, with the burden of proof on the person who received the summons, that he or she did in fact purchase a muni-meter ticket prior to or up to five minutes thereafter from the issuance of the summons and that the receipt is valid for use at the time and location where such summons was issued. Such defense shall be deemed established if such person produces the actual muni-meter receipt or a copy thereof at such prosecution or proceeding. For the purposes of this section, 'muni-meter' shall mean an electronic parking meter that dispenses timed receipts showing the amount of parking time purchased.
