Use it when someone has won by a large margin and there's no doubt about their victory.

Clear Winner

Describes a situation where there is no real competition due to obvious difference in skill or ability.

Non-Competitive

Can be used metaphorically to express an easy victory in any comparison, not just physical competitions.

In legal contexts, it means accepting a charge without admitting guilt to avoid a trial.

By pleading no contest, a defendant doesn't directly say they did the crime but accepts punishment.
