tion to be imposed for a violation of the rules.
In a spell of speciousness, the plaintiff argues that dismissal is too drastic a sanction because the defendants could have uncovered his falsehood earlier if they had diligently pursued their discovery rights. We are as unpersuaded by that argument as we would be by one from an embezzler who blamed his victim for not uncovering the misappropriation scheme earlier.
Dismissal with prejudice is, as we have said, an extreme sanction, see Goforth, 766 F.2d at 1535, but it is justified in extreme circumstances. This is another way of saying that the sanction imposed should fit the interests jeopardized and the harm caused by the violation. In this case it does. Because courts must be able to preserve the integrity of the judicial process, we have no hesitation in concluding that a party who files suit under a false name and proceeds with that deception right up to trial loses the right to seek judicial relief for the claims he was advancing.
AFFIRMED.
APPENDIX A
THE COURT: In this case, the Plaintiff, whose true name is Cesar Vasquez, filed two separate complaints, both filed under penalty of perjury, under a false name, the false name being Yan Zocarras.
In this case, the Plaintiff filed two separate affidavits of indigency. And in those affidavits of indigency the first portion of the affidavit says, “I” — and then a blank for the name, in which he filled in the name Yan Zocarras.
Both of those affidavits were filed under a false name.
For the two separate cases concerning five convictions in the State of Florida, both of those convictions were under false names. The first conviction was under the name Yan Michael Zocarras; the second conviction was under the name Carlos Vasquez.
So as he stands today in the Department of Corrections for the State of Florida— and there have been two Department of Corrections officers here every day, along with the United States marshals, to guard this state prisoner. He remains under a false name.
The Plaintiff when he was arrested in the underlying facts of this civil rights action gave the false name Carlos Vasquez, which he testified in open court he knew was a lie.
He also testified that he knew that there was an open case against him at the time that he gave the false name of Carlos Vasquez, rather than giving his other false name, which was Yan Michael Zocarras.
While the Plaintiff on recall did testify that he was told he had to use the name under which he was sentenced, and it seems the inference is that since his first conviction was under the false name Yan Michael Zocarras in the State of Florida, he was eventually committed to the Department of Corrections under the false name Yan Michael Zocarras with the alias of Carlos Vasquez and several other aliases.
At no time did the Plaintiff reveal to either the state court system or the State Department of Corrections that his true name is Cesar Vasquez. As far as they’re concerned, he’s still Yan Michael Zocarras, also known as Carlos Vasquez, also known as Miguel Vasquez, also known as Luis Garcia, Yan M. Zocarras, Yan Michael Zo-carras.
Nowhere in the Department of Corrections information is the name Cesar Vasquez. And in fact, the first time it was
