Shaun Andrew Blake and Martin John Mace have both been charged with one count of assault.

The pair have pleaded not guilty.

In court on Monday, Mr Blake was represented by lawyer Dan Coombes.

Mr Mace was represented by lawyer Mark Doyle.

The trial began in front of Chief Justice Alan Blow.

It is alleged Mr Blake and Mr Mace became enraged with Angela Rosette Cuskelly on the night of August 1, 2014.

It is alleged the pair struck her with a torch and beat her near Ravenswood after claiming she had stolen a wallet from them that contained $3000.

It is then alleged the pair drove her to a house at Invermay where they beat Ms Cuskelly with a fishing rod, a steel cap boot, their fists and feet, and then poured a flammable liquid on her and threatened her.

Both lawyers adamantly denied the allegations against their clients.

“The Crown says Mr Blake was involved … What is the evidence? Is it reliable?” Mr Coombes asked the jury.

“Mr Mace did not commit this offence,” Mr Doyle said.

Crown prosecutor Peter Sheriff compared the state’s case against Mr Blake and Mr Mace to a cricket match.

“You can never score a run without someone down the other end,” Mr Sheriff said.

“It’s a partnership. It is possible to have one set of particulars with two people involved.”

Ms Cuskelly was the first witness to give evidence at the trial.

She told the court she barely knew either man and that she was driving around Launceston with them on Friday, August 1.

Ms Cuskelly said that night she had returned home when she was allegedly interrupted by the pair at her door.

She claimed they were “yelling hysterically” and one of them broke a window, claiming she had stolen $3000 from them.

Ms Cuskelly alleged they forced her to look for a wallet containing the cash, hit her with a torch when she couldn’t find it near Ravenswood, and the abuse continued into the early hours of Saturday morning.

She told the court she eventually escaped the situation and sought help from a nearby BP fuel station.

The trial continues on Tuesday.
