Pamela Mattock Porter is making another bid to get out of jail before her money laundering trial begins.

In court on Friday her lawyer successfully petitioned to have another bail hearing, arguing that new evidence can demonstrate she is not a flight risk.

That new evidence will include testimony from her daughter, who did not appear before the court during Mattock Porter's first bail hearing.

Prosecutors said they would likely present new evidence at that next bail hearing, which is scheduled for July 30. Her preliminary inquiry is to begin on Sept. 16.

Mattock Porter was arrested earlier this year in Panama, then extradited to Canada last month to face charges of laundering money as part of an alleged scheme involving $22.5 million in bribes.

Porter's husband, Arthur, is accused of masterminding the plot and remains in prison in Panama where he is fighting his extradition to Canada. The pair left Canada and spent several months in the Bahamas, with Arthur Porter supposedly receiving treatment for lung cancer, before they went to Panama.

Mattock Porter is the only member of the alleged plot to not be granted bail, with former SNC-Lavalin president Pierre Duhaime, vice-president Riadh Ben Aissa, businessman Jeremy Morris and Porter's assistant Yanai Elbaz, have all obtained bail in exchange for amounts between $50,000 and $100,000.

SNC-Lavalin has filed a civil lawsuit against Ben Aissa and others alleging they conspired to use company funds to smuggle the son of former Libyan dictator Moammar Gadhafi to Mexico.
