Nothing in Section 5.06.010 hereof shall be construed to prohibit the conduct of social card games at those locations within the city vested with such right at the time of passage of Ordinance 1120. All vested rights held by virtue of having previously operated a social card game within the city or by having filed a completed application for the conduct of such social card games shall end and be null and void if such location is not used for the conduct of social card games for a period of two years, regardless of whether the owner or person, persons, firm or corporation in control of such location intends to abandon such use or not. The period of two years shall commence to run from December 11, 1999 for any location which claims vested rights but is not presently operating an establishment for the conduct of social card games. The period of two years for any establishment operating social card games on the date of passage of Ordinance 1120 shall commence on the date such conduct ceases. (Ord. 1160 §1, 2001; Ord. 1120 §2, 1999).
