Report of the Special Master received and ordered filed. The Court notes that the Master has twice directed the parties to address whether the amount of damages at stake justifies further proceedings. The Master’s Report and the submissions of the parties indicate that fees and expenses could well exceed any recovery. The parties are therefore directed to consider carefully whether it is appropriate for them to continue invoking the jurisdiction of this Court. See Arizona v. California, 373 U. S. 546, 564 (1963) (“[W]e are mindful of this Court’s often expressed preference that, where possible, States settle their controversies by mutual accommodation and agreement.” (internal quotation marks omitted)). The Special Master is encouraged to facilitate efforts to resolve the parties’ dispute without the need for a damages proceeding, including by revisiting the arrangement for division of fees and expenses. Cf. Fed. Rule Civ. Proc. 68. If the parties elect to continue, exceptions to the Report, with supporting briefs, may be filed within 45 days. Replies, if any, with supporting briefs, may be filed within 30 days. Sur-replies, if any, with supporting briefs, may be filed within 30 days
