No person shall be ineligible for appointment and no person shall be denied employment as a firefighter or as a police officer in a city or town because of failure to attain a minimum height unless the administrator, in response to the written request of the appointing authority that no person under a specified height be certified for appointment to such position in said city or town, has established a minimum height requirement for the position. Such request shall include the findings of a validation study demonstrating the necessity for a minimum height for said position in said city or town, and such other evidence as the administrator may require.

No person shall be certified for original appointment to the position of firefighter or police officer in a city or town which has not accepted sections 61A and 61B if that person has reached 32 years of age on or before the final date for the filing of applications, as stated in the examination notice, for the examination used to establish the eligible list from which the certification is to be made.
