There's some big questions here, most prominently what qualifies as a reimbursable expense. Montenegro is claiming that Pearce should be reimbursed for all of the campaign costs ($260,302), though others claim that at best it should be limited to his own personal expenses, not funds he raised and spent.
Here is a previous look at the question of recall reimbursement.
Until 1973, state law included provisions to reimburse recalled officials: maximums of $500 for statewide officers, $200 for legislators and $150 for municipal officers. However, that law was repealed as part of a sweeping overhaul of the state’s initiative, referendum and recall statutes.And the only time it came up was when Governor Evan Meacham faced a recall (that never occurred because of his impeachment). Here's what happened:
When Mecham requested an advance payment of $1.5 million to fund his campaign, Attorney General Bob Corbin issued an opinion that said the Legislature must enact a provision to make the payment, as one does not exist in statute – and that the amount reimbursed could be whatever lawmakers choose.
