The amendments are intended to address issues of timeliness and efficiency. A 90-day timeframe for a decision is seen as reasonable and is in keeping with labour code practices of other tribunals. There isn't a way to arbitrarily decide whether or not it's a win. I believe the minister has the power to extend that deadline beyond the 90 days for certain provisions, but I need to check that as well and get back to you. Really it is aimed at providing for more timely decisions, which both employers and employees are interested in having in these cases.
