Roberto Pigilan, a.k.a Bert Control, contracted Hansen's disease (Leprosy), exhibiting open lesions. A law requires that lepers be isolated upon petition of the City Health Officer. The wife of Bert wrote a letter to the City Health Officer to have her philandering husband confined in some isolated leprosarium. Bert challenged the constitutionality of the law, as violating his liberty of abode. Was there a violation of the liberty of abode?
