Adds "substantial need for treatment" as a criterion for civil commitment of mentally ill persons, defined by specific criteria including high probability of severe harm if untreated, impaired capacity to make informed treatment decisions, and reasonable prospect of treatability.

Extends early intervention treatment orders from 90 days to 12 months and initial commitment periods from 6 months to 12 months for mentally ill, developmentally disabled, or chemically dependent persons.

Allows emergency holds and peace officer custody based on substantial need for treatment meeting the new criteria, not just danger to self or others.

Prevents revocation of advance psychiatric directives during the first 90 days of court-ordered early intervention treatment.

Requires commissioner of human services to review and propose conforming legislation for the 2017 session to address implementation and conflicts with the new treatment need criteria.
