The petition may describe the act or acts complained of, if applicable, in concise language, give a detailed description including the approximate date, location and nature of each act complained of, be signed by the person making the charge, give his respective post office address and be verified, under oath, that he believes the charge or charges to be true and that he has knowledge of the alleged facts relating to the charges if any have been alleged in the recall petition.
