A Perth vegan has taken her neighbours all the way to the Supreme Court, demanding they stop smoking, bouncing balls and even cooking barbecues in the backyard.

Cilla Carden, from Girrawheen, in Perth's northern suburbs said she's fed up with the smell of meat cooking on the barbecue next door.

"They've put it there so I smell fish, all I can smell is fish. I can't enjoy my backyard, I can't go out there."

Ms Carden, a massage therapist, is also furious at cigarette smoke wafting into her yard and the sound of children playing with basketballs next door.

"It's been devastating, it's been turmoil, it's been unrest, I haven't been able to sleep," she said.

But one neighbour invited 9News into the backyard, to show that he's removed the barbecue and told his children to stop playing basketball.

Ms Carden is so upset she has taken her neighbours to the State Administrative Tribunal and the Supreme Court.

"It's deliberate, that's what I told the courts, its deliberate."

But a Supreme Court Judge and the State Administrative Tribunal have sided with her neighbours, dismissing her case.

Her request to appeal the decisions has also been refused.
