George J. Spencer and Rosanna M. Spencer (Appellants) appeal from an order of the Court of Common Pleas of Montgomery County (trial court) granting summary judgment in favor of the Commonwealth of Pennsylvania (Commonwealth) because the Commonwealth, was immune from suit, and because Appellants failed to name a commonwealth party before the statute of limitations had run. We affirm.
Appellants filed a wrongful death and survival action on October 25, 1982, for damages resulting from their daughter’s death on June 29,1982, in a four-vehicle accident. One of the original defendants filed a joinder complaint against the Commonwealth demanding indemnity or contribution. The caption of the joinder complaint named the party as the “Commonwealth of Pennsylvania.” The joinder complaint, however, did refer to the Department of Transportation as the agency responsible for highway design and maintenance, and concluded with the following language:
WHEREFORE, the additional defendant, DEPARTMENT OF TRANSPORTATION, COMMONWEALTH OF PENNSYLVANIA is either alone liable to the Plaintiffs, *429is liable over to the Defendant, GREG PAVLIK, or is jointly and severally liable with one or all of the other defendants in the litigation upon the causes of action that have been declared upon by the Plaintiffs.
On August 8, 1984, a Petition to Consolidate was filed by the Attorney General’s office, requesting that the above-captioned matter be consolidated with three other pending cases which had been filed as a result of the same accident. This petition contained the following allegation and request for relief:
1. The Commonwealth of Pennsylvania, Department of Transportation is a named Defendant in the four (4) cases listed above.
WHEREFORE, The Commonwealth of Pennsylvania, Department of Transportation respectfully requests this Honorable Court to grant this petition to consolidate the above matters under the Court terms and numbers.
This petition was stricken without prejudice by the trial court on September 24, 1984, for failure of petitioner to appear. A second petition for consolidation, containing similar language, was filed on August 11, 1987, and granted on October 8, 1987.
After the jury was impaneled, the Commonwealth moved for summary judgment on the grounds that it was immune from suit, and that no Commonwealth party had been named prior to the expiration of the statute of limitations. The trial court granted summary judgment in favor of the Commonwealth. This appeal followed.
The Appellants’ basic argument is that leave to amend the joinder complaint should have been granted to permit a change in the designation of the governmental party from “Commonwealth of Pennsylvania” to “Commonwealth of Pennsylvania, Department of Transportation.”
Summary judgment may be granted only “if the pleadings, depositions, answers to interrogatories and ad*430missions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” Pa.R.C.P. No. 1035(b). Our scope of review of a trial court’s grant of summary judgment is limited to a determination of whether the trial court abused its discretion or committed an error of law. Herman v. Greene County Fair Board, 112 Pa.Commonwealth Ct. 615, 535 A.2d 1251 (1988).
This case, once again, requires this court to address the issue of when a pleading can be amended to change the designation of a party after the statute of limitations has run. This issue has been before us previously in three reported decisions.1 In Hall v. Acme Markets, Inc., 110 Pa.Commonwealth Ct. 199, 532 A.2d 894 (1987), we held that the Commonwealth is an entity distinct from the agencies and employees encompassed in the term “commonwealth party” as defined in the immunity statute, 42 Pa.C.S. § 85012. We held further that only commonwealth parties may be sued for damages, and that pursuant to 1 Pa.C.S. *431§ 23103 and 42 Pa.C.S. § 8522(a)4 the Commonwealth itself is absolutely immune from suit. In Hall we permitted the amendment of the complaint because DOT had been involved in all aspects of the litigation from its inception: the Secretary of DOT had been named in the original complaint.
The second case where we addressed this issue was Bainbridge v. Department of Transportation, 125 Pa.Commonwealth Ct. 406, 557 A.2d 456 (1989). In Bainbridge the plaintiffs sought damages for injuries sustained when their car slid on an icy spot on a state highway located in Mt. Pocono, Pennsylvania, and near the Pocono Mountain Campsites. The plaintiffs filed a trespass action against the township, the Commonwealth, and the campsite. The Commonwealth filed preliminary objections in the form of a motion to dismiss the complaint, on the basis that the complaint did not name a commonwealth party and that the Commonwealth was absolutely immune from suit. Plaintiffs then filed an amended complaint which named DOT as a defendant in place of the Commonwealth. The Common*432wealth filed preliminary objections on behalf of DOT, alleging that DOT was a new and distinct party and that the statute of limitations had run before the amended complaint had been filed. We held that DOT was a distinct party and that the exchange of letters between the “Tort Claims Unit” of the Bureau of Risk and Insurance Management in the Department of General Services (DGS) was not involvement of DOT in all aspects of the litigation after the suit was filed. Accordingly, we held that naming DOT as a party, after the running of the statute of limitations, was not the correction of a technical ciefect, and would be prejudicial to DOT. We affirmed the trial court’s dismissal of the complaint.
Finally, in Garcia v. Commonwealth, 131 Pa.Commonwealth Ct. 327, 570 A.2d 137 (1990), the plaintiff sought damages for injuries sustained in a slip and fall accident which occurred at the intersection of Sixth and Clearfield Streets in Philadelphia. The plaintiff notified the Office of Attorney General that she intended to file a claim, and when she filed her complaint, she identified the party in the caption as the Commonwealth, and within the body of the complaint as the Commonwealth of Pennsylvania, Office of Attorney General. The Commonwealth filed an answer and new matter raising the defense of sovereign immunity, and a motion for judgment on the pleadings, alleging that it was not a proper party. The plaintiff responded to the motion for judgment on the pleadings by arguing that the Commonwealth and DOT were not distinct parties, and that a fair reading of the complaint illustrated that DOT was the intended defendant. The plaintiff also argued that DOT had participated in the litigation after the suit was filed as a result of an investigation made by DGS at the prelitigation stage. The plaintiff sought leave to amend the complaint to substitute DOT for the Commonwealth and to preclude DOT from raising the statute of limitations as a defense. The trial court denied the Commonwealth’s motion for judgment on the pleadings, granted plaintiff leave to amend her complaint by substituting DOT for the Commonwealth, and *433barred DOT from raising the statute of limitations as a defense.
We reversed the order of the trial court, holding that the plaintiff was on notice from the moment DGS responded to his claim letter that the proper party was DOT, not the Commonwealth, and that DOT’s response to a request for information from DGS was not participation in litigation as in Hall, to permit the substitution of parties.
In the instant matter the only references to DOT in the original pleadings was a paragraph of the third-party complaint stating that the legislature had imposed upon DOT the duty to construct, improve, maintain, and repair the highways within the Commonwealth of Pennsylvania, and the above-cited language of the ad damnum clause of the same document. However, the paragraph of the complaint setting forth the negligent conduct which is being complained of states that it was “the carelessness and negligence of the COMMONWEALTH OF PENNSYLVA-NIA____” not some act of DOT which was at issue.
Appellants argue that the naming of the commonwealth agency within the body of the joinder complaint, as well as in the ad damnum clause, combined with the Commonwealth’s use of the agency name in a motion to consolidate and responses to discovery, indicate that DOT was actually involved in the case from its inception, so as to permit the amendment of the joinder complaint to formally name DOT as a party, after the expiration of the statute of limitations. However, Appellants ignore the fact that the attorney of record filed his appearance on behalf of the Commonwealth only. The mere reference to a separate and distinct party in a motion, body of a pleading, or ad damnum clause, is as a matter of law, insufficient to make that party a participant in the action. The rules of civil procedure require that the party be named in the caption, and the failure to so name a party is not a mere technical error that can be corrected after the statute of limitations has run. The *434naming of a party after the running of the statute of limitations is prejudicial, and will not be permitted.
Accordingly, we affirm the order of the trial court5.
ORDER
AND NOW, May 2, 1991, the order of the Court of Common Pleas of Montgomery County in the above-captioned matter is affirmed.
. We note with disapproval that the trial court, in its opinion, and both parties before this court, cited to our unreported decision in Verna v. Commonwealth of Pennsylvania, No. 843 C.D. 1988, filed April 28, 1989. Citation to Verna is prohibited by Section 414 of the Commonwealth Court of Pennsylvania Internal Operating Procedures which reads as follows:
Report of Opinions; Certain Decisions not to be Cited — Unreported opinions of the court shall not be cited in any brief, argument or opinion, except that any opinion filed in the same case may be cited as representing the law of the case. A one-judge opinion, even if reported, shall be cited only for its persuasive value, not as a binding precedent. This rule shall be effective retroactively, so as to apply to opinions filed before the effective date of this section, as well as to opinions filed in the future. (Emphasis added.)
. This section reads in pertinent part as follows:
“Commonwealth party." A Commonwealth agency and any employee thereof, but only with respect to an act within the scope of his office or employment.
. This section reads as follows:
§ 2310. Sovereign immunity reaffirmed; specific waiver
Pursuant to section 11 of Article I of the Constitution of Pennsylvania, it is hereby declared to be the intent of the General Assembly that the Commonwealth, and its officials and employees acting within the scope of their duties, shall continue to enjoy sovereign and official immunity and remain immune from suit except as the General Assembly shall specifically waive the immunity. When the General Assembly specifically waives sovereign immunity, a claim against the Commonwealth and its officials and employees shall be brought only in such manner and in such courts and in such cases as directed by the provisions of Title 42 (relating to judiciary and judicial procedure) unless otherwise specifically authorized by statute.
. This section reads as follows:
§ 8522. Exceptions to sovereign immunity
(a) Liability imposed. — The General Assembly, pursuant to section 11 of Article I of the Constitution of Pennsylvania, does hereby waive, in the instances set forth in subsection (b) only and only to the extent set forth in this subchapter and within the limits set forth in section 8528 (relating to limitations on damages), sovereign immunity as a bar to an action against Commonwealth parties, for damages arising out of a negligent act where the damages would be recoverable under the common law or a statute creating a cause of action if the injury were caused by a person not having available the defense of sovereign immunity.
. Our resolution of this issue makes it unnecessary for this court to address the other issues raised by the Appellants: (1) whether the granting of summary judgment on the basis of Crowell v. City of Philadelphia, 131 Pa.Commonwealth Ct. 418, 570 A.2d 626 (1990), was proper when no testimony had been taken; and (2) whether the trial court abused its discretion in denying Appellants’ motion to compel discovery after certification for trial, when counsel had stipulated to continued discovery.
