The easiest. although incomplete, way for most people to find case law seems to be through Google Scholar( searching only Texas cases). Alternatively, you can usually access Nexis through many county law libraries without being a lawyer. Of course, just finding the cases isn't the same as understanding their legal weight or import.

Some interesting case law that is at least tangentially related to CHL/weapons:
1. As far as I know, there are four cases dealing with 46.035, two dealing with failure to conceal and two dealing with carry while intoxicated.
2. The only case that I am aware of for 30.06 (issued earlier this year) did not address the argued question of whether or not the lack of Spanish rendered a sign invalid because the case was reversed on jurisdictional issues.
3. Although there is a lot of use of force case law, the most interesting set of cases seems to be those that a blow or blows to the face are not considered deadly force.
4. There are a pair of cases on how the blade of a knife is to measured for unlawful carry of a weapon charges (everything past the hilt or guard, not just the sharpened area).
5. A lot of the case law dealing with 46.03 has been superseded by changes to the definitions, especially regarding premises.
