Liberal MP Kevin Andrews says Islamic bakers should be able to refuse to bake cakes for Jewish weddings and vice versa.
The former minister told Sky News this kind of refusal of service would fall under the religious protections he would like to see in the Marriage Act.
Mr Andrews said protections provided in Dean Smith’s bill are ‘woefully inadequate’.
‘This goes to fundamental religious beliefs and beliefs of conscience and it’s only in relation to that,’ he said.
