As I've said, I do think “obtain for consideration” has a meaning in law, and that reimbursement of legitimate medical expenses would not be captured by that phrase.
I would like to point out that the Istanbul declaration and other health-related instruments really are focusing on the non-commercialization principle which we have in Canada in all of the human tissue gift acts. There is consensus that organs should not be commodified or commercialized internationally. Where there isn't consensus is on this type of offence, and where you extend extraterritorial jurisdiction over people—sick people—who go abroad to purchase life-saving organs from people they believe are consenting.
On that issue, it's criminal law, meaning that it's not a fine or a general civil ban; it's incarcerating people upon their return from receiving an organ, while they're healing. There isn't consensus on that, not even in the criminal treaties we have. The Council of Europe treaty specifically leaves it to independent states to determine whether or not they're going to extend their criminal law in that way. It's my understanding that only a very few countries, a handful, actually use the criminal law to address transplant tourism.
