Homelessness case before US supreme court could have far-reaching effects

Justices to consider constitutionality of punishing people for sleeping outside as western states seek to address encampments

A case that could significantly change how US cities respond to the growing homelessness crisis has reached the supreme court as record numbers of people in America find themselves without a permanent place to live.

The justices on Monday will consider a challenge to rulings from a California-based appeals court that found punishing people for sleeping outside when shelter space is lacking amounts to unconstitutional cruel and unusual punishment.
