During a trial, the defendants brought a motion to exclude a new reply report by the plaintiffs' expert, Dr. John Bradford.
The plaintiffs sought to introduce the report to address six questions they claimed arose unexpectedly from the defendants' experts' testimony.
The court reviewed the principles governing late-filed expert reports, noting they are only admissible to address new, unanticipated matters raised by the defence.
The court analyzed each of the six questions and found that only one (Question 4, regarding the difference between segregation in a hospital versus a prison setting) addressed a genuinely new opinion.
The motion to exclude was partially granted, with only Question 4 of the reply report admitted.
