rationale

Canada's Supreme Court overturned a lower court ruling that the sale of BCE, the parent of telecommunications holding company Bell Canada, to the Ontario Teachers' Pension Plan and its minority U.S. partners didn't adequately consider bondholders' interests.

The court's rationale for its unanimous decision is to be released later.

Can I replace rationale with reasons?
Thanks
