Tasmania's Law Reform Institute is pushing for a ban on male circumcision.

The institute claims that the laws governing non-therapeutic male circumcision in Tasmania are so unclear, it is not certain if it is even legal.

A report recommends a general ban on infant circumcision unless there is an established religious or customary reason.

It also recommends new laws, setting out whether or not it is legal for an adult, or a capable minor, to request circumcision.

The institute also wants to clarify what happens if parents disagree on whether a circumcision should be done and says a circumciser who fails to meet a certain standard of care should be criminally liable.

Institute director Professor Kate Warner says the investigation attracted 126 submissions from local, national and international respondents.
