You might think that as soon as a bill is approved by the Legislature, it heads to the governor's desk. But there's a process including getting all the needed signatures, some last proofreading and something called enrolling and engrossing a bill.
This is a total insider thing here, but the bills this year seem to be taking a little longer than usual to reach the fourth floor. No one is panicked yet, but I'm hearing grumbling about the slowness. Richardson's office needs time to look over the final version of a bill, and in particular bills that make simultaneous changes to the same part of law.
One example is the open conference committees bill, which the governor can't act on until he gets, but there are many others still in the pipeline. Richardson has until April 10 to act.
