Me. Rev. Stat. tit. 26, § 666

The director may not issue to an employer for a person with a disability a special certificate authorizing the employer to pay that person a wage less than the minimum wage, based on the ability of the person to perform the duties required for that employment in comparison to the ability of a person who does not have a disability to perform the same duties. An employer may not pay less than the minimum wage to a person by virtue of that person's having a mental or physical disability. A special certificate authorizing the payment of less than minimum wage to a person with a mental or physical disability issued pursuant to a law of this State or to a federal law is without effect.
