MONTREAL - Quebec's controversial protest law is set to face its first challenge in court.

Lawyers representing student federations and other groups will be in Quebec Superior Court today seeking to have certain parts of Bill 78 suspended.

It's one of two legal motions filed last week against the emergency law adopted earlier this month to crack down on recent student protests.

The first motion, to be heard beginning today, seeks to suspend sections of the law that involve public protest.

The second motion is to have Bill 78 declared invalid altogether and it will be heard at a later date.

The government argues the law preserves the rights of students to attend school, while also respecting free speech.
