The move to change Tasmania's anti-discrimination laws is in limbo.

The Upper House last week blocked a Government push to ban conduct that ridicules or humiliates a person because of their disability, sexual orientation, and political or religious beliefs.

A majority of MLCs backed a Liberal argument that the changes would restrict freedom of speech.

The Attorney-General Brian Wightman has not decided what to do with the legislation, which is now back in the Lower House.

The Anti-Discrimination Commissioner Robyn Banks hopes the Government will push through with the changes.

"The protection should be extended to all, and the reason for that is that the kind of conduct that we're talking about is not the kind of conduct that a reasonable person engages in," she said.

Ms Banks hopes the issue will be dealt with this week.
