1. The trial court was correct in granting plaintiff's post-trial motion to amend the pleadings to make Hydro-Air Engineering,
Inc., originally a third-party defendant, a direct party defendant where Hydro-Air Engineering, Inc. impliedly consented to
trial of the issue of its liability to plaintiff. Minn. R. Civ. P. 15.02. 2. The evidence adduced at trial was sufficient to support the jury's findings that defendant designer was negligent in designing
the product, that defendant designer had supplied defendant manufacturer of the product with a defective design for the product,
and that defendant designer's negligence was a direct cause of 55% of plaintiff's loss.
