A public servant has failed to convince a magistrate he suffers from a mental impairment that led to him to masturbate in a car park in front of a woman who told him to "put your dick away".
Brendan Allan Hall, 35, fronted the ACT Magistrates Court on Monday after pleading guilty to indecently exposing himself in public in Gungahlin in April last year.
Hall was in his black Audi when he drove past and then parked next to a woman, who did not know him, in an empty car park on Anzac Day afternoon.
