SIMON O'CONNOR (National—Tāmaki): Point of order. Thank you, Madam Chair. It is just to seek your ruling on the first part of the Hon Michael Woodhouse's notion that, after a Minister speaks, there has been a tradition or a convention in this House that further calls could be had. It would be useful, if you're going to continue to put the vote, to indicate to the committee if that convention is going to change.
