Former Victorian cabinet minister Theo Theophanous is charged with raping the woman in 1998.

A committal proceeding for Theophanous in the Melbourne Magistrates' Court was told Theophanous knew the woman socially and invited her to have a look at Parliament House after they had late-evening drinks nearby.

After a brief tour of Parliament House, Theophanous tried to get the women to enter an amphitheatre but the woman refused, prosecutor Michelle Williams SC told the court today.

It is alleged Theophanous and the woman then went to his office where he raped her on a red couch.

As the pair left Parliament House, Theophanous allegedly told the woman: "What I like about you is that you are loyal".

Theophanous's lawyer Robert Richter, QC, described the woman as being manipulative and a fabricator of stories.

"There will be evidence that she created evidence, that she falsified evidence, that she lied," Mr Richter said.

"This is the evidence of one woman against one man, a woman motivated by spite."

Magistrate Peter Reardon and prosecution and defence teams are to go on a view of the alleged rape scene later today.

The hearing continues.
