If you accept the assertion that countries are allowed to police their borders as they see fit, sans abuse and neglect, then it justifies it on the basis of "reasonable practice." This was a discretionary entry and discretion was withheld. Then again, as I pointed out elsewhere, my angst is not with the author of the article, just the comment to which I replied.
(I happen to subscribe to the theory that, since the world is highly unlikely to do the reverse, borders should be relaxed to the point where people can move as freely as capital, but we're not anywhere close to that, either.)
