Steven Tyley was caught red-handed in June 2003 dumping half a tonne of broken asbestos sheets in Cardiff - "showing complete disregard" for the safety of nearby residents.
Appearing before Cardiff magistrates on 21 January, Mr Tyley was found guilty of illegally disposing of controlled waste. He received a 12-month conditional discharge and was ordered to pay only one quarter of the council's costs in bringing the case to court.
The council noted that measures now before Parliament will enable officers to issues fixed penalty notices for traditional fly-tipping offences - "but this sort of offence involving hazardous waste will still be taken to court. In this instance it is the council tax payer that has paid the majority of the costs."
