The OMB has distributed the following invitation for a webinar primer on the new Local Planning Appeal Tribunal which members may be interested in attending. The webinar is free but you must preregister. Note that it says that the new rules will come into effect on April 3rd. At the OSSGA Conference, a presentation was made which included speculation on what the implications of the new system could be, and timelines on transitioning to the new LPAT system. It is available in the members area of the website, and for members' convenience I have attached it here. We will continue to monitor and keep you posted on this issue.
