§ 4110. Challenges for cause. (a) Challenge to the favor. The fact that a juror is in the employ of a party to the action; or if a party to the action is a corporation, that he is a shareholder or a stockholder therein; or, in an action for damages for injuries to person or property, that he is a shareholder, stockholder, director, officer or employee, or in any manner interested, in any insurance company issuing policies for protection against liability for damages for injury to persons or property; shall constitute a ground for a challenge to the favor as to such juror. The fact that a juror is a resident of, or liable to pay taxes in, a city, village, town or county which is a party to the action shall not constitute a ground for challenge to the favor as to such juror. (b) Disqualification of juror for relationship. Persons shall be disqualified from sitting as jurors if related within the sixth degree by consanguinity or affinity to a party. The party related to the juror must raise the objection before the case is opened; any other party must raise the objection no later than six months after the verdict.
