District of Columbia Court of Appeals August 30, 1985, 82-1139 (Sinai v. Polinger Co.)

NEBEKER, Associate Judge,

concurring:

Appellants raise objections to, among other things, the trial court’s instructions on assumption of the risk and contributory negligence. It is well settled that appellants bear the burden of affirmatively establishing prejudicial error. Goldstein v. Kennedy, 134 A.2d 580, 581 (D.C.1957); D.C.Code § 11-721(e) (1981).
