OOPS: $1.9 billion Medi-Cal error adds to California deficit projection.

The administration discovered accounting mistakes last fall, but it did not notify lawmakers until the administration included adjustments to make up for the errors in Brown’s budget proposal last week. The Democratic governor called for more than $3 billion in cuts because of a projected deficit he pegged at $1.6 billion.

“There’s no other way to describe this other than a straight up error in accounting, which we deeply regret,” said H.D. Palmer, a spokesman for the Department of Finance.

The agency followed its normal practice by waiting to report the errors in the governor’s next budget, he said.

Brown’s deficit projection was driven by more than just the accounting error, Palmer said, noting that California tax collections came in below expectations for most of the first half of the fiscal year.

The massive hole in the Medi-Cal budget surprised state lawmakers.

It always does.
