Some testimony that complainants hoped would bolster their case in the moose collision lawsuit was not accepted by the judge on Thursday.
Historian Bob Cuff had prepared a report that covered topics such as wildlife management and how to prevent moose-vehicle collisions.
Justice Robert Stack said that he could not accept these areas of the report, ruling that Cuff did not have enough expertise on those topics.
The defence for the province is also challenging the expertise of former bureaucrat Ron Penney.
Penney has prepared a report that says public servants did not provide politicians with the necessary information about how to handle moose on highways.
Stack will rule about Penney's testimony on Friday.
The trial began Wednesday with personal stories from victim's of moose-vehicle collisions.
The case has been working its way to trial since St. John's lawyer Ches Crosbie officially filed the claim in January 2011.
Crosbie is spearheading the class action lawsuit against the provincial government on behalf of the victim's of moose-vehicle collisions.
