The Probation and Parole Act [31-21-3 to 31-21-19 NMSA 1978] shall be liberally construed to the end that the treatment of persons convicted of crime shall take into consideration their individual characteristics, circumstances, needs and potentialities as revealed by case study, and that such persons shall be dealt with in the community by a uniformly organized system of constructive rehabilitation under probation supervision instead of in an institution, or under parole supervision when a period of institutional treatment is deemed essential in the light of the needs of public safety and their own welfare.
