Texas Forgery Law, The Crime Confirmed by the 277th District Court
(This news item supports Mowdy's "Williamson County's Culture of Corruption" speech.)
The contractor falsely swore, in writing a document was the contract act of Tom Mowdy, and filed that writing in two official proceedings. First, a lien claim then in a lawsuit. Texas Penal Code Chapter 32 Fraud Sec. 32.21 defines those acts as forgery.
When committed twice, the intent to harm is presumed. When committed against an elderly person, the charge is elevated to the next higher level.
The contractor himself confirmed the document was false with his two conflicting sworn statements.
