You haven't provided sufficient information to answer your question. What motion was filed? What stage is the litigation in? Is the case at issue? Has discovery been completed? Has a trial date been set? Without more information, your question cannot be answered. However, it is always permissible for the parties to agree to mediation, and they can do that at any time. If you want to go to mediation quickly, you can always ask the other side (through your attorney, if you are represented) whether it will agree to mediate the dispute sooner rather than later.
I agree with Mr. Hassen, the question does not provide enough information. Was the motion to set mediation? Sometimes mediations take months to set up because of calendar conflicts between the attorneys, clients and mediators.
