Justice Mata Keli Tuatagaloa upheld an appeal on the charge of negligent driving causing injury and convicted Mauga of the charge on Friday.
His ruling overturns a decision by the District Court in December last year to acquit Mauga of the charge.
Justice Tuatagaloa also dismissed an appeal on a charge of failure to stop and ascertain.
The appeal was filed by Satiu Simativa Perese, an independent prosecutor, hired by the Attorney General’s Office.
The charges against Mauga stemmed from a three-vehicle accident on Beach Road in Apia, last year.
