This seems a tad harsh, but I suppose if there were concrete evidence of abuse, then by all means, the authorities should intercede.
The opening paragraph of the editorial also refers to the Canadian Criminal Code:
Polygamy has been a crime in Canada since 1892. Under s. 293 of the Criminal Code any conjugal union with more than one person at the same time, whether or not it is a binding marriage, is an indictable offence with a penalty of up to five years in prison.
There's no ambiguity in s. 293. Polygamy is illegal, no ifs, ands or buts.
Under that definition, any 'conjugal union' of consisting of more than two people is illegal.
However, I wonder how many consensual living arrangements there are in Canada involving more than two persons? We are already told that Swingers' sex is legal by the Supreme Court. So is it only legal in clubs? What if the couples want to live together in a conjugal manner? So they have to go the the clubs to have sex?
So what we're talking about here is polyamory. I really don't think that law from 1892 is valid any longer. Society and morals have changed, I am always being told.
Supposing two bi-sexual women and a straight guy all love each other and want to live together, and possibly even have that recognized as a civil union?
How can we stop it?
On what legal grounds?
