OPINION OF THE COURT

Allen N. Brunwasser appeals from an order entered in the District Court granting Defendant’s motion to dismiss his claim challenging the constitutionality of Rules 3305, 3306, and 2744 of the Pennsylvania Rules of Appellate Procedure, which generally grant authority to the Prothonotary of the Pennsylvania Supreme Court and to the state’s appellate courts to recommend and/or institute sanctions against attorneys for violations of various rules, including the filing of frivolous appeals. Brunwasser brought suit individually and as a representative of a class of lawyers potentially affected by the aforementioned rules, naming several of his clients as additional plaintiffs. Brunwasser’s claim was dismissed for lack of standing. We will affirm.

As the District Court noted, this is not the first time that Brunwasser filed such a lawsuit. In fact, he filed a “nearly identical action” on July 9, 2001, which was dismissed with prejudice for lack of standing. 1 See D. Ct. Order at 2 (citing Brunwasser v. Johns, No. 01-1255, 2002 WL 32775 (W.D.Pa. Jan.10, 2002)). Brunwasser appealed, and we subsequently affirmed. (Brunwasser v. Johns, 52 Fed. Appx. 185, 186 (3d Cir. 2002)).

Brunwasser now asks us to reverse the District Court’s most recent ruling because he contends that: 1) certain proposed amendments to his complaint, which establish that Brunwasser is fearful about pursuing various legal issues because doing so may result in the imposition of sanctions against him, confer the standing necessary to revive his claim, and thus, the case should be remanded for further consideration on the merits; 2) the District Court’s order, which cautioned Brunwasser against filing baseless lawsuits in the future or else face the prospect of Rule 11 sanctions, constitutes a “gag order,” which in itself confers standing upon Brunwasser; and 3) the Court’s order, which in addition to warning Brunwasser about future sanctions also noted that his claim could be barred by res judicata, qualifies as an advisory opinion, or, in the alternative, suggests that the District Court Judge was acting as a biased advocate.

*411 It is well settled that in order to establish Article III standing, the plaintiff must show, inter alia, that he “suffered an injury in fact — an invasion of a legally protected interest [that] is ... concrete and particularized” and “actual or imminent, not conjectural or hypothetical.” AT & T Communs. of N.J., Inc. v. Verizon N.J., Inc., 270 F.3d 162, 170 (3d Cir. 2001) (citing Lujan v. Defenders of Wildlife, 504 U.S. 555, 560-61, 112 S.Ct. 2130, 119 L.Ed.2d 351 (1992)). Furthermore, fear of a possible future consequence that is merely speculative is not an injury in fact, and thus is not sufficient to confer standing. See, e.g., Georgine v. Amchem Prods., 83 F.3d 610, 636 (3d Cir. 1996), affd sub nom. Amchem Prods, v. Windsor, 521 U.S. 591, 117 S.Ct. 2231, 138 L.Ed.2d 689 (1997).

In the instant case, Brunwasser’s allegations regarding the potential imposition of sanctions against him is nothing more than speculative. Furthermore, his assertions (1) that a court’s forewarning of possible future sanctions is equivalent to a “gag order,” 2 (2) that the delivery of such a warning makes a judge into a biased advocate, and (3) that a court violates the rule against issuing an advisory opinion when it merely notes that there are other bases on which its ruling could be supported, are wholly lacking in merit.

For the foregoing reasons, we find Brunwasser’s contentions without merit. Accordingly, we will summarily AFFIRM.
