The Court of Appeals yesterday rejected a request for a retrial made by two former Bangkok-based policemen who were both handed 20-year prison terms for raping a minor while in custody seven years ago.
The presiding judges said there was no new evidence that supported their petition based on the court procedural regulations.
The ruling came despite the victim previously saying she gave false testimony during earlier court proceedings.
The request for a retrial was lodged in February by the wives of the ex-officers.
The Supreme Court recently upheld the verdicts of the lower court.
Mongkhol Thothong and Nulom Adma, who were senior sergeants-major at Phet Kasem police station, were found guilty of raping the girl, then 16, while she being detained on criminal charges in 2007.
The Court of Appeals said the men could have filed a false-statement charge against the victim during earlier court proceedings but they filed it during the Court of Appeals stage, before the Supreme Court had upheld the convictions.
In the victim's statement in which she "admitted to lying:, she said she felt guilt over testifying falsely. However, the Court of Appeals deemed that she might have been motivated by other reasons.
The woman was sentenced to nine months' jail for perjury last December.
