tortfeasor

1. (law) A person who commits a tort.Examples: "[…] there is an exception “in the cases of heir and executor, who may plead a release to the ancestor or testator whom they respectively represent; so also with respect to several tortfeasors, for in all these cases there is a privity between the parties which constitutes an identity of person”."; "Damages paid by the settling tortfeasor which are greater than the pro rata amount can easily be attributed to his desire to avoid legal fees and bad press, or misspeculation about the merits and likely outcome of the case."
