What characterizes a Texas post-adjournment veto?

A Texas post-adjournment veto is characterized by its absolute nature since the legislature is not in session at the time the veto is issued. This means that once the legislature has adjourned, it cannot convene to override the veto. The governor's decision effectively becomes final, preventing any further legislative action on the bill until the next session. This unique aspect of the post-adjournment veto underscores the power the governor wields in terms of bill enactment, as it eliminates the possibility for legislative rebuttal or modification at that particular moment.

In contrast, other forms of vetoes, such as regular vetoes during a legislative session, allow for the possibility of an override if the legislature acts accordingly. The specifics regarding duration for enactment or limitations to tax bills do not pertain directly to the nature of a post-adjournment veto itself. The distinct time constraint of the legislature not existing to take action further solidifies the idea that once the governor takes this step, the bill is effectively nullified until a future session.
