4109 - Peremptory Challenges.

§ 4109. Peremptory challenges. The plaintiff or plaintiffs shall have
a combined total of three peremptory challenges plus one peremptory
challenge for every two alternate jurors. The defendant or defendants
(other than any third-party defendant or defendants) shall have a
combined total of three peremptory challenges, plus one peremptory

where a side has two or more parties, the court, in its discretion, may
allocate that side's combined total of peremptory challenges among those
parties in such manner as may be appropriate.
