MEMORANDUM

Riverside County Office of Education (“RCOE”) challenges a ruling by a California administrative law judge (“ALJ”) that required RCOE to provide speech and language services to J.H. and ordered RCOE to petition to, intervene in a state juvenile court proceeding to identify a locked residential treatment center placement for J.H.

RCOE has fully satisfied the terms of the ALJ’s order relevant to this appeal; there is no further action that RCOE is required to take. Indeed, the state juvenile court denied RCOE’s motion to intervene, J.H. was never placed in a residential treatment /¡enter, direct appeals from J.H.’s state court juvenile proceedings have since concluded, and the record does not indicate that there are any pending collateral attacks on those proceedings. The only relief the ALJ ordered that RCOE challenged in its briefs as inappropriate was the order requiring RCOE to petition to intervene in a state juvenile court proceeding and to identity a locked residential treatment center placement for J.H.

“As a prerequisite to our exercise of jurisdiction, we must ... satisfy ourselves that this case is not moot.” Biodiversity Legal Found. v. Badgley, 309 F.3d 1166 , 1173 (9th Cir. 2002) (citing Cole v. Oroville Union High Sch. Dist., 228 F.3d 1092 , 1098 (9th Cir. 2000)). Even if neither party contends that the case is moot, “we have an independent duty to consider sua sponte whether [it is].” Demery v. Arpaio, 378 F.3d 1020, 1025 (9th Cir. 2004) (citing Dittman v. California, 191 F.3d 1020, 1025 (9th Cir. 1999)). “Where the activities sought to be enjoined already have occurred, and the appellate courts cannot undo what has already been done, the action is moot, and must be dismissed.” Foster v. Carson, 347 F.3d 742, 746 (9th Cir. 2003) (quoting Bernhardt v. County of Los Angeles, 279 F.3d 862, 871 (9th Cir. 2002)); see also EEOC v. Fed. Express Corp., 558 F.3d 842, 846-47 (9th Cir. 2009) (“The test for mootness of an appeal is whether the appellate court can give the appellant any effective relief in the event that it decides the matter on the merits in his favor. If it can grant such relief, the matter is not moot.” (quoting In re Burrell, 415 F.3d 994 , 998 (9th Cir. 2005))).

Here, “declaring the [ALJ’s order] unlawful would serve no purpose,” Ctr. for Biological Diversity v. Lohn, 511 F.3d 960, 964 (9th Cir. 2007), because such a declaration would not affect RCOE’s duties or actions in this case. We “cannot undo what has already been done,” and everything RCOE properly challenges in this appeal has already been done. Foster, 347 F.3d at 746 (quoting Bernhardt, 279 F.3d at 871 ). The appeal is therefore moot and must be dismissed.

DISMISSED.

This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. . We consider any arguments not "specifically and distinctly” raised in the opening brief to be waived. Greenwood v. FAA, 28 F,3d 971, 977 (9th Cir. 1994). . Accordingly, we deny as moot RCOE's motion for judicial notice.
