Proposed religious discrimination laws could make it legal for a boss to tell a gay worker "being gay is a form of brokenness", or a childcare provider to tell a single mother "God will judge you harshly for taking away the child's right to have a father".

As public submissions close on the second draft of the Morrison government's religious discrimination bill, Monash University associate professor of constitutional law Luke Beck warned the revised bill included provisions that "appear to be motivated by a desire to allow people to be nasty to others".

In a separate submission, the 13-member Australian Discrimination Law Experts Group (ADLEG), said the bill was "deeply flawed", prioritising religious beliefs over the rights of LGBTIQ Australians, people with a disability and women.

The ADLEG, which includes Sydney University professor Simon Rice and Melbourne University professor Beth Gaze, said the bill's wide definition of "statements of belief" meant current unlawful acts of discrimination would "likely become lawful if based on religious belief".
