Not explicitly.
This is part of the relevant law:
- PC §9.32. DEADLY FORCE IN DEFENSE OF PERSON. (a) A person
is justified in using deadly force against another:
...
(2) if a reasonable person in the actor's situation would not have
retreated; and ...
However, district attorneys rarely prosecute people for failing to retreat, especially in cases of home invasion.
There was an exceptional case. In 1996, a gentleman named Gordon Hale defended himself against an assault, and the Dallas district attorney attempted to prosecute him. The grand jury declined to issue an indictment. This was the first attempt to prosecute a CHL holder for defending himself, to my knowledge.
The NRA-ILA will try to get the Texas law amended in the next legislative session.
