Arkadiusz Robert Swiebodzinski, 25, faces court over burglary, trespassing charges

A request to remove the night-time curfew from an animal activist's bail conditions was denied by the Mandurah Magistrate on Friday.

Animal rights group Direct Action Everywhere member Arkadiusz Robert Swiebodzinski, 25, appeared in the Mandurah Magistrates Court on July 12 with an application of variation of bail, citing his employment as the reason to remove the curfew.

He said he was required to work all hours of the day and night as a truck driver and his curfew was therefore impacting on his ability to work.

The East Perth man had previously pleaded not guilty to stealing a Fresian calf worth $1500 from a Brunswick dairy farm on October 23, 2018.

He also pleaded not guilty to trespassing on a Nambeelup farm and aggravated burglary and commit.

Mr Swiebodzinski's bail conditions were imposed after he faced Bunbury Magistrates Court on May 9. Additionally, he was ordered not to enter any farms, stockyards, feeding lots, or places where animal husbandry occurs and must not enter any points of international departure.

Mr Swiebodzinski unsuccessfully tried to vary his bail conditions and request a curfew change in Bunbury Magistrates Court on July 1.

Police prosecutor Diana Flint said she strongly opposed the application because all of Mr Swiebodzinski's alleged offences occurred during the night.

Sergeant Flint told the court the prosecution was "concerned" the group's "organised meetings" would continue after dark.

"We're trying to stop the offending from happening," she said.

"It appears this group is hellbent on disrupting the day-to-day activities of farmers and the like."

Mr Swiebodzinski told the court he saw "no consistency" between his bail conditions and those of his co-accused.

"Two other co-accused have no curfew even though they have more charges than me," he said.

Sergeant Flint said it was something the prosecution was trying to change.

"The co-accused unfortunately don't have curfews but this is the next thing we will address."

Magistrate Vivian Edwards said Mr Swiebodzinski had not presented any evidence of current employment or a letter from his employer proving that he needed to work after daylight hours.

"You've not provided any confirmation of employment, whether you're a truck driver and what your hours of work are," she said.

"Without that, your application will fail. Your application is deficient."

Mr Swiebodzinski is due to reappear in the Mandurah Magistrates Court on August 16.
