Section 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.
