One major difficulty that faces both researchers and practitioners who
work with the homeless is the lack of definitions and frameworks that
assist better understanding of such people's problems and society's r
esponse to them. This article reviews the legislation dealing with hom
eless people's social, civil and legal problems. We tried to give this
legislation's historic and social background, including a section on
psychiatric disorders in this group because of their relevance to curr
ent debate on homeless offenders. We then reviewed the legislation rel
evant to homeless people in general and the homeless mentally ill in p
articular, including the recently introduced court diversion schemes.
