Earlier this year, courts in Tonga dealt with a much more high-profile bribery case when former Prime Minister Lord Tu'ivakano was charged with accepting bribes in a passport approval case.
The bribery charges alleged that between 2013-2014, while Foreign Affairs Minister, Tu'ivakano accepted money for the issuance of Tongan passports to various Chinese nationals.
In March, Tu'ivakano was eventually found guilty of three charges, including making a false statement for the purpose of obtaining a passport and perjury.
In April he received a two-year sentence, fully suspended and a fine for passport, perjury and firearm offences.
