Here are the updated materials in the case now captioned Grand Canyon Skywalk Development LLC v Cieslak (D. Nev.):
Defendants seek to amend their answer to allege a counterclaim against the Plaintiffs. The proposed counterclaim alleges two causes of action: abuse of process and intentional interference with prospective economic relations. Plaintiffs oppose the motion on the grounds that it is untimely, will cause undue prejudice to them and that the proposed counterclaim would be futile because neither cause of action states a legally viable claim for relief.
