For three years, Mr Mah Kiat Seng was on a one-man crusade to get the courts to review his conviction for refusing to cooperate with the police.
He launched attempt after attempt to overturn it, and even took the case to the highest court of the land.
Yesterday, the High Court decided that enough was enough. He had exhausted his right to appeal, and will no longer be able to take further legal action on his conviction without the court's permission.
Mr Mah's persistent legal proceedings were "vexatious", said Justice Lee Seiu Kin in a judgment published yesterday.
They were also "without any reasonable ground" and took up the court's valuable time and resources.
It all began in 2009, when Mr Mah, now 39, was arrested for causing grievous hurt.
At the police station, he refused to have his fingerprints, photograph and blood sample taken.
The following year, he was convicted by a district court for one charge of refusing to have his fingerprints and photograph taken by the police and one charge of refusing to give a blood sample.
Mr Mah, who is now unemployed, was fined $500 on each charge.
He paid but appealed to the High Court in 2010 and succeeded in being acquitted on the blood sample charge as proper procedures were not followed.
But Mr Mah would not let the matter rest.
On the other charge, he twice applied to refer questions of law to the Court of Appeal.
