He did comment on the England controversy last year
"The interesting bit here is that the referee actually stopped the clock, asked Owen Farrell to speak to his players about their discipline, quite rightly so and very good refereeing management by the referee then.
"But, I think, then you must check that they're ready before you restart the game. So personally, if I was refereeing, I would have checked to make sure that England were ready."
On the potential Louis Rees-Zammit knock-on in the build-up to Liam Williams' try, Owens added: "If a player loses control of the ball forwards, i.e. off his hand, he has to regain possession of that ball before it touches the ground or hits another player, or even travels backwards afterwards. Otherwise, it's a knock on.
"So, imagine a player going for an interception sticks his hand out, juggles the ball upwards, which is travelling forwards but fails to catch it so knocks it backwards. That is still deemed a knock-on because he's failed to regain possession of the ball.
"So, in this instance, my humble opinion is Rees-Zammit's hand clearly touches the ball, the ball is then travelling forward as is Rees-Zammit before it then hits his thigh, then off the back of his leg and then backwards.
"So, because Rees-Zammit failed to regain possession of the ball, under law, that then is a knock-on. But also, as I said, we must appreciate these decisions are always difficult decisions to make."
