I'm with you. A major expenditure like that should have been discussed with the board first. The question of whether or not the president "can" make that decision without input from the board is really a matter of your own group's policies. You can use this situation to put a policy in place that all expenditures over a certain amount must be approved by the board. You should make the amount fairly large. You want your president to be able to make quick decisions when needed, but you don't want her to hamstring your future operations.
Check your bylaws and make sure there needs to be a executive team vote. Agreed, it is the ENTIRE Executive team that should vote and make decisions regarding the budget.
I agree, check your bylaws. Most bylaws state that items over a certain dollar amount need to be approved by the board and possible all members of the pto.
