Do you have any appeal rights following the decision?

No.  There are no appeal rights following the issuance of an appeal decision.  However, you may file a motion for reconsideration of the final decision if extraordinary circumstances are established.  You must file this motion within 10 days of the date on which the General Counsel's final decision is postmarked.  See 5 C.F.R. § 2423.11(g).
