1. Whoever makes a promise to the public of a prize to be given for a specific act and sets a time limit therefor, shall be bound to give the prize to whoever performs this act in accordance with the announced conditions, even if they performed it without regard to the promise of the prize. 2. If the promisor does not set a time limit for the performance of the act, they may revoke their promise by a public announcement, provided that this does not affect the right of any person who has completed the act before the revocation of the promise. No claim for the prize shall be heard after the lapse of three (3) months from the date of the announcement of the promisor's revocation.
