The former Solomon Islands attorney-general Julian Moti has won a battle to have child sex charges against him dropped.
Mr Moti was arrested at Brisbane International Airport in December 2007 and charged with seven counts of engaging in sexual intercourse with a person under the age of 16.
The AAP news agency says the charges related to the alleged rape of a 13-year-old girl in Noumea and Vanuatu in 1997.
Since his return to Australia Mr Moti has fought to have the charges thrown out.
His lawyers argued his deportation from Solomon Islands was unlawful because it was an abuse of procedure.
Yesterday, a Brisbane judge ordered all charges against Mr Moti be dropped.
