A group that promotes African trophy hunting has asked a Calgary judge to order protesters to stop insulting event attendees.

The Calgary chapter of Safari Club International (SCI) is seeking an injunction against Mike Donovan, the founder of Ban African Trophy Hunting (BATH) and owner of an African photo tourism company called Lion Dog African Safaris.

SCI has a booth at The African Show — an event organized by African Events Inc. that promotes African travel and hunting. Donovan is alleged to have engaged in "wrongful behaviour" during protests outside the trade shows, which are held annually in Calgary, Saskatoon and Toronto.

SCI and African Events aren't asking protesters stay home, just to choose their phrasing more carefully, according to lawyer Christa Nicholson, who represents both organizations.

She told Court of Queen's Bench Justice Richard Neufeld that protesters can yell "stop trophy hunting," but can not insult attendees with words like "shame," "unethical," and "immoral."

Those words, said Nicholson, amount to defamation.

"That is his opinion," said Neufeld of Donnovan's protest statements. "Your client holds the opinion that trophy hunting is moral and ethical; these are opinions."

'Aggressive yelling'

But Nicholson argued the opinions are defamatory and should be stopped by a judge's order. BATH protesters, she said, are involved "aggressive yelling" and "extremely alarming" statements.

"Opinions can be expressed, but they're not to be defamatory ones," said Nicholson.

Donovan, who represented himself, said this is an issue of freedom of expression.

"This is an injunction [application] to shut me up," said Donovan, who represented himself at the hearing. "The plaintiffs are playing the victim here."

Neufeld has reserved his decision. The Africa Show is set to take place in Calgary, Saskatoon, Montana and Florida in January.
