Actually you articulated what I was thinking. If the unsworn affidavits were materially the same I don't think they can claim "It was a surprise!"
Chupp could have sat down and compared the two submissions if he was so inclined, right? The PDF's didn't get deleted off the server.
He could have looked into it himself rather than just listen to Lemoine.
This was one of Ty's most egregious mistakes, in my opinion. When submitting affidavits to the court, a party can object to either the FORM of the affidavit or the SUBSTANCE of the affidavit.
See e.g. Dailey v. Albertson’s, Inc., 83 S.W.3d 222, 225 (Tex.App.–El Paso 2002, no pet.)
If there is a defect in form (ie. it wasn't properly notarized), then Texas law says that the party supplying the affidavit automatically gets an opportunity to cure the defect. This is because courts don't want to throw out a case just because a notary didn't stamp a piece of paper correctly.
If there is a defect in substance (ie. the party is obviously lying, or doesn't know what they're talking about), then there is no automatic right to cure.
Clearly, a fucked-up notarization is a defect in form of the affidavit. Ty, were he an experienced litigator, would know that he has a legal right to cure that defect by just submitting the affidavit with a correct notarization.
Instead, Ty WITHDREW the affidavits altogether, and then tried to refile them with an amended petition. While the practical difference isn't huge, procedurally, this is an EPIC FUCKUP. When there is an objection to the form of an affidavit, you respond by filing an affidavit with the defect cured, not by withdrawing the affidavit, which WAIVES your right to cure. Instead of taking his automatic re-do on the affidavit, which he was legally entitled to receive, Ty tried to sneak the affidavits in an arguably late-filed amended petition.
In other words, he got caught trying to sneak in the back window when the front door was wide open and available.
