Even amongst conservatives, the issue has become contentious. The Maxim Institute has announced its opposition to binding citizens referendums, citing the adverse fiscal management consequences that have ensued in the state of California in a recent paper from Richard Ekins, a University of Auckland legal academic. Former New Zealand Prime Minister John Key also opposes binding referendums on fiscal grounds, noting that California's contradictory tax cap and public spending referendums have made state fiscal management chaotic. However, a key problem with that argument is that ballot initiatives only make up 2% of the Californian state budget, once Proposition 98 is removed from the equation (Proposition 98 locks in education spending which probably would have been spent anyway and had always occupied about one-third of the Californian budget).
