A Brisbane magistrate has dismissed charges against four people accused of the 'Satanic' vandalism of graves at Toowong Cemetery last year, in part because it could not be proven the group did not have permission to do so.

Zoe Louise Wilson, 24, Benjamin Lionel Garland, 19, Shane Alan Bell and Michael John Smallbon, both 27, walked free from Brisbane Magistrates Court this afternoon following the decision.

The foursome had been charged with the wilful damage of 82 graves at the historic cemetery in August last year.

The court heard one of the group bragged about inverting crucifixes at the cemetery because it "had meaning to Satanists".

But following evidence from several witnesses at a committal hearing yesterday, lawyers for the four accused today argued their clients had no case to answer.
