I like to think we are getting in to spring. That new life is on the verge of breaking free of the currently cold and fetid ground. That Persephone is not held up on some unusually difficult underworld errand. That we may again be renewed.

In that spirit of renewal, I bring you the opinion in Ferrer Int'l S.A. v. Verge Analytics Inc., C.A. No. 24-694-RGA (D. Del. Feb. 24, 2026). That case dealt with a surprisingly novel set of facts.

The plaintiff filed a complaint and the defendant filed counterclaims, which the plaintiff answered. Then, there was an amended complaint, followed by amended counterclaims that were identical to the original counterclaims. The answer to those counterclaims, however, was different from the previous answer, with some allegations that were previously admitted now denied.

The defendant moved to strike these changed responses to the counterclaims, "premised on the theory that Plaintiff could not substantively change its responses to the unchanged allegations of the counterclaims."

In the spirit of the season, Judge Andrews denied the motion, finding that the plaintiff was free to start anew, unfettered by its old responses:

In this case, Plaintiff was required to respond to Defendant’s amended pleading. Plaintiff was not limited to copying its previous response to the counterclaims. It could treat them as new counterclaims.

Id. at 2.

And so let us all bask in the coming light of a new and stronger sun. Free to reconsider old bargains and break new ground.

I am so cold.

  • While counterclaims are generally low-cost, they are not free and still involve some work.
  • They increase the risk that the defendant, who is now a counterclaim-plaintiff, will have to bring some subset of its witnesses to Delaware for deposition.
  • They may have little impact on how the case progresses.

These days, however, the pendulum seems to be swinging back to some extent, with parties …
