Charges against the man behind a parody Campbell Newman Twitter account have been dropped almost two months after he was arrested wearing an "I'm with stupid" T-shirt on the election campaign.

Iain Fogerty's case drew international attention when he was charged with public nuisance following complaints to police after he stood near LNP campaigners wearing the now infamous shirt.

The New Farm man, a vocal critic of the former government through his Not Campbell Newman Twitter account, said he wasn't surprised to see the charges dropped but they should never have been brought in the first place.

"The fact that police were called at all was an extreme overreaction," he said.
