It would mean that an interim order couldn't continue for more than a year. I would suggest that it's not so much a sunset clause as a limitation on interim orders so that they can't be used as a loophole. There would have to be valid reasons for that interim order. To add the element around public consultations is important, but that is something that the commission can fix and put into place as well.
I would suggest that it's limiting a loophole and ensuring more public transparency.
