So, the key date is the date that that State Court of Criminal Appeals would hear the case.
That was June 14, 2014. However, "If the court overrules the previous appeals court decision, DeLay's attorney, Brian Wice, still has one appeal left with the original appellate court in Austin."
The result, a good one, is that Travis County is now picking up a trimmed-down tab for their Public Integrity (Political Prosecution) Unit, forcing them to lay off ten staffers and reduce their case load. Cost was no object when the whole state was paying for it. Now Travis County must put its money where its mouth is.
This is a much better outcome than leaving the burden on State taxpayers and only getting a two-year DA appointment before the County elects another Ronnie Earle.
If what you are saying was in fact part of the motivation for the veto, I sure wouldn't be talking about it with Perry facing a criminal indictment over the same facts. It sounds, however, like some speculation from last June.
