Conventions
It is often a constitutional convention that the upper house may not block supply. There is often another requirement that non-money bill type clauses may not be attached to a money bill.
Loss of supply in the lower house is conventionally considered to be an expression of the house's loss of confidence in the government resulting in the government's fall.
