Under the act, persons who solicit sex " Persons associating in a "prostitution establishment" with another person for the purpose of prostitution faces a jail term or a fine or both. The term "prostitution establishment" is not clearly defined, although it may be broadly interpreted to include any place where prostitution takes place, especially in regard to cases involving child prostitution that carry heavier penalties up to six years if the prostitute is younger than 15 years of age βotherwise, the law is not usually enforced against prostitution in private places.
The act also imposes heavier penalties against owners of prostitution businesses and establishments.

Additionally, any offense under Section 9 that is committed "by means of fraud, deceit, threat, violence, [or] the exercise of undue influence or coercion," results in a penalty that is "one-third heavier". The Act was also written to address child prostitution, but lacks complete clarity, as it does not define what an "indecent act" is.
