"no clear way forward" 
A referendum to find out of if the public wanted change - as recommended by the all parliamentary committee - would have been a "clear way forward. Of course it would likely have given an answer the Liberals didn't want. They have been completely self serving on this right from their false promises in the election. This is no different than a previous Liberal government's campaign promise of "We'll eliminate the GST"... they lie and they don't care. $10B deficits? 25000 refugees by Dec 31? Clearly they are willing to say anything if they think it will get them elected.
