How can a Beis Din issue a ruling on this without both sides present?
There needs to be a zablo set up where both sides make their cases to determine the ruling on this matter.
Of course botei din will by default say it’s proper to keep paying! They don’t want to be responsible for yeshivos collapsing, and worst case scenario, it’s tzedaka anyway.
The admin of my child’s school refused any discounts, saying they will collapse if they offer such a thing. I told him that as long as this is the policy across the board I will continue paying as a tzedaka, but if I find out that he gave anyone any discounts, I will be calling him back and demanding my money back. It’s either a discount for everyone or for no-one.
