A, a minor, while riding in an automobile driven by B, his father, sustained injuries in a collision with an automobile driven by C. A sued C, and the latter impleaded B on a cross-complaint for contribution. The jury found the injuries to be the result of the concurring negligence of both defendants. The cross-complaint was dismissed. Held, that since there could be no recovery against the father by his son, no right of contribution existed. Zutter v. O'Connell (Wis. 1930) 229 N.W. 74-
