Three men have pleaded guilty to a single count of forgery in relation to the passing of NCT tests.
The men, including two former NCT workers, appeared in court this morning.
They pleaded guilty to a single count of forgery, but also face charges of corruption.
It relates to allegations that they took bribes in exchange for certificates of road-worthiness.
The three men are due before the court again in October, as is another former NCT worker who was not present in court today.
