Me. Rev. Stat. tit. 17-A, § 1703

Except when specifically precluded, in choosing the appropriate punishment for an individual convicted of a crime, the court shall consider the desirability of imposing a sentencing alternative involving a fine either in conjunction with or in lieu of a sentencing alternative involving imprisonment. A sentencing alternative involving imprisonment may not be imposed by a court solely for the reason that the individual does not have the present or future financial capacity to pay a fine.
