In determining whether or not there is a reasonable prospect, the WRA will consider if there is a legal or factual reason which means that the loss can never be used.
Wrth ddyfarnu a oes disgwyliad rhesymol ai peidio, bydd ACC yn ystyried a oes rheswm cyfreithiol neu ffeithiol sy’n golygu na fydd byth modd defnyddio'r golled.
