Frequently Asked Questions
What law governs injunctions in Texas?
The principles and practice of equity, except where they conflict with the rules or statutes (Rule 693).
What happens if equity principles conflict with the rules in a Texas injunction case?
The rules and statutes control. Rule 693 applies equity's principles and procedure only when they are not in conflict with the rules or the governing statutes.
Does Rule 693 create new grounds for a Texas injunction?
No. It borrows the established practice and procedure of courts of equity to fill gaps the rules and statutes leave open, not to create new grounds for relief.
