Jury charges that combine liability and defenses (wonky post)

The losing party in Alonso v. Westcoast Corp., No. 17-30877 (Apr. 8, 2019), contended that it was plain error to submit the below jury question about a contract claim, without also asking whether the plaintiff had itself breached:

The Fifth Circuit held that it was not plain error, noting that earlier in the charge as part of the instructions, the jury had been told that if “one party to a contract substantially breaches the contract, then the breaching party cannot enforce the contract it has breached or demand damages form the other party to the contract.” The Court cited Baisden v. I’m Ready Prods., Inc., 693 F.3d 491, 506 (5th Cir. 2012), which allowed a question that “conflated the question of license (an affirmative defense . . . ) with that of infringement (a claim on which [plaintiff] carried the burden),” even though that  question was “not a model of clarity.”

This was a Louisiana case; by way of comparison (background only, given the deferential standard of review in this case), the Texas pattern charge on this point uses questions about both parties’ breach, drawing from Mustang Pipeline Co. v. Driver Pipeline Co., 134 S.W.3d 195 (Tex. 2004).
