He was seen wearing the epaulettes and sleeve lace of a Rear Admiral, a two-star position that is one of the highest ranks in the Royal Navy, at the event in November.
Carley, from Harlech in Gwynedd, was seen walking in formation to the war memorial before a wreath was laid by another individual, and then saluted at the war memorial before marching away.
Concerns were raised by serving and former service personnel.
Llandudno Town Council, which organised the Remembrance event, confirmed that no-one of the senior rank had been due to attend the ceremony.
Carley faced a single charge of being a person not serving in HM military forces, wearing without His Majesty’s permission a uniform and dress bearing the regimental or other distinctive mark of the military force, namely The Royal Navy.
The court was told that is an offence under the Uniforms Act, which dates back to 1894.
