Paxton’s approach also subverts what the Legislature intended when it passed a law in the 1990s that required plaintiffs to file lawsuits in counties where a “substantial” part of the alleged violation took place, according to three legal experts. That was done at the behest of conservatives who felt trial lawyers were flocking to venues favorable to them to win big damage verdicts against businesses.

“It looks like the attorney general’s office is interested in engaging in litigation games that it would otherwise decry if the shoe were on the other foot,” said Michael Ariens, a professor at St. Mary’s University School of Law in San Antonio, who has studied laws regulating where lawsuits can be filed.
