Yes, I think the first year or two would be a good indication of where the problems lie. Administrative tribunals—and I'm not an expert in the one that you've been hearing about, the veterans pension appeal board—are typically haunted by backlogs, delays, and injustices suffered in the hearing process. All these problems are within the authority of the ombudsman.
If you're going to cut the pension appeals board out of the ombudsman's mandate, it would be better not to create the office at all. This is the meat and potatoes of what an ombudsman does. If the government creates an ombudsman that can't oversee this board, don't bother. Call it something else, because it won't be an ombudsman. This is how crucial oversight of this body is.
