§ 2851. Age not to be bar to employment by public authorities. No
public authority shall hereafter prohibit, prevent, disqualify or
discriminate against any person applying for employment by, such
authority, who is physically and mentally qualified, or from competing,
participating or registering for a position, or be penalized in a final
rating for any position, by reason of his or her age. Any existing rule,
regulation, penalty or requirement resolution preventing the hiring of
persons because of age shall be void, except that nothing herein
contained, shall prevent any public authority from adopting reasonable
minimum or maximum age requirements for positions such as police
officer, firefighter, guard or other positions which require
extraordinary physical effort except where age limits for such positions
are already prescribed by law.

Notwithstanding any provisions to the contrary, no person who is
physically or mentally qualified may be disqualified from, competing,
participating or registering for a promotional examination or be
penalized in a final rating or barred from promotion after having passed
such promotion examination by reason of his or her age, by any public
authority.
