It depends on what you're studying and how many witnesses you want to call. For example, the fisheries committee predominantly has witnesses from the east and west coasts, so their budget is a lot higher for witnesses than that of a committee that would call witnesses from the immediate area. If you have a study that's ongoing for three or four years, or a year, and you're going to call people from overseas, from Europe and so on, the budget will depend on what your plans are.
