OTTAWA - Conservatives hope to mop the courtroom floor with former cabinet minister Helena Guergis's $1.3-million lawsuit against them when the case goes before a judge next week.

A hearing on Wednesday in Ottawa will deal with five motions from all the defendants in the case to dismiss Guergis's claims that Prime Minister Stephen Harper, the Conservative Party and others defamed her and conspired to "engage in unlawful acts" to kick her out of the party in 2010.

Guergis's expulsion followed allegations about her personal behaviour.

Back in May, the defendants asked the judge to dump Guergis's "vexatious" complaints, arguing that her dismissal from cabinet is the prime minister's prerogative and that the party has the right to drop her as a candidate.

On Thursday, Guergis fired back at the dismissal motions, arguing that the defendants "inaccurately summarized" her claims and are trying to get out of a lawsuit "without any defences having been delivered."

There have been suggestions the weakest part of Guergis's lawsuit is against the Conservative Party itself.

In its motion to dismiss the lawsuit, the party argues it isn't "a legal entity capable of being sued" in the case.

Lawyers for Guergis and several defendants declined comment.
