OPINION OF THE COURT
HUTCHINSON, Justice.
Ronald and Frances Gajkowski, Robert Schipske and William and Jean Abate (appellants) appeal by allowance a Superior Court order 350 Pa.Super. 285, 504 A.2d 840 which reversed an order of an en banc panel of Bucks County Common Pleas. Appellants brought suit in Common Pleas against appellees, International Brotherhood of Teamsters, [519]*519Chauffeurs, Warehousemen and Helpers of America (IBT) and Highway Truck Drivers and Helpers Local Union No. 107 (Local 107), for damages stemming from a shooting on January 25, 1980 at a plant at which members of Local 107 were on strike and picketing. A jury returned a verdict in favor of appellants. An en banc panel of Bucks County Common Pleas affirmed. Concluding that there was insufficient evidence to warrant holding the appellees liable, Superior Court reversed. Our examination of the record leads us to hold that Superior Court properly exonerated the IBT from liability. However, there is sufficient evidence from which the jury could properly hold Local 107 liable for damages resulting from the shooting. Therefore, we affirm that portion of Superior Court’s order relating to IBT and reverse the order relieving Local 107 of liability.
On November 18, 1979, the members of Local 107 employed at the Minnesota Mining and Manufacturing Company’s (3M) Bristol plant voted to commence a lawful economic strike after rejecting 3M’s final offer for a new collective bargaining agreement. After the strike vote, Local 107 initiated around-the-clock picketing at the entrance to the Bristol facility. The picketing remained uneventful until January 25, 1980, when Robert Ballinger, a member of Local 107, shot Ronald Gajkowski, Robert Schipske and William Abate with a .22 caliber revolver.1 Gajkowski and Schipske were members of Local 107 and Abate was a security guard at the 3M plant. As a result of the shooting, Gajkowski lost his left eye, Schipske suffered injuries to his nose and Abate sustained severe internal injuries.
Appellants filed a complaint in trespass in Bucks County Common Pleas against Local 107 and its parent organization, the IBT. Following a lengthy trial, the jury was instructed on common law negligence principles and the stricter proof requirements incorporated in Pennsylvania’s Labor Anti-Injunction Act. Although Common Pleas held that the act’s strict limitations on union liability for civil [520]*520damages did not apply to the facts of this case, the jury was presented with special interrogatories on both theories of liability. The jury found in favor of the appellants on both theories and awarded damages totaling approximately 1.3 million dollars.2 Common Pleas, sitting en banc, denied appellees’ post-trial motions seeking arrest of judgment, judgment non obstante verdicto or a new trial. Holding that the Labor Anti-Injunction Act applies, Superior Court determined that the appellants offered insufficient evidence to support the verdicts and entered judgment n.o.v. We granted appellants’ petition for allowance of appeal because of the important questions raised on union liability under this act for injuries arising out of violence during strikes.
I. INTRODUCTION
Section 8 of Pennsylvania’s Labor Anti-Injunction Act, Act of June 2, 1937, P.L. 1198, No. 308, 43 P.S. § 206h (Anti-Injunction Act), sets out both the kind and degree of proof necessary to hold a labor organization liable for the acts of officers, members or agents:
No officer or member of any association or organization, and no association or organization participating or interested in a labor dispute as herein defined, shall be held responsible or liable in any civil action at law or suit in equity or in any criminal prosecution for the unlawful acts of individual officers, members or agents, except upon proof beyond a reasonable doubt in criminal cases, and by the weight of evidence in other cases, and without the aid of any presumptions of law or fact, both of — (a) the doing of such acts by persons who are officers, members or agents of any such association or organization; and (b) actual participation in, or actual authorization of, such acts, or of ratification of such acts after actual knowledge thereof by such association or organization.
[521]*52143 P.S. § 206h. Arising from the troubled labor history which precedes the Great Depression, the act reflects a legislative decision that crippling judgments against labor organizations in unfriendly forums threaten workers’ rights to collective bargaining. Anti-Injunction Act, supra, § 2, 43 P.S. § 206b(a). See also Western Pennsylvania Hospital v. Lichliter, 340 Pa. 382, 387, 17 A.2d 206, 209 (1941). The Pennsylvania statute closely parallels the language of Section 6 of the Norris-LaGuardia Act, 29 U.S.C. § 106 (1982), which reflects the same concern.3 In Philadelphia Marine Trade Ass’n v. International Longshoremen’s Ass’n, 453 Pa. 43, 308 A.2d 98 (1973), noting the similarities in the two statutes, we stated that the United States Supreme Court’s interpretation of Section 6 of the Norris-LaGuardia Act offers guidance in our construction of Section 8 of the Anti-Injunction Act. Examination of the myriad of opinions of other state and federal courts in this area also offers insight into the competing policy considerations in this area of labor relations.4
The background of Section 6 of the Norris-LaGuardia Act was explored in United Brotherhood of Carpenters v. United States, 330 U.S. 395, 67 S.Ct. 775, 91 L.Ed. 973 (1947). There, the Court held that the unique language of the Norris-LaGuardia Act precludes the employment of either standard agency or respondeat superior analysis to hold a union vicariously liable for the torts of its officers, members and agents:
[522]*522We hold, therefore, that “authorization” as used in § 6 means something different from corporate criminal responsibility for the acts of officers and agents in the course or scope of employment. We are of the opinion that the requirement of “authorization” restricts the responsibility or liability in labor disputes of employer or employee associations, organizations or their members for unlawful acts of the officers or members of those associations or organizations, although such officers or members are acting within the scope of their general authority as such officers or members, to those associations, organizations or their officers or members who actually participate in the unlawful acts, except upon clear proof that the particular act charged, or acts generally of that type and quality, had been expressly authorized, or necessarily followed from a granted authority, by the association or non-participating member sought to be charged or was subsequently ratified by such association, organization or member after actual knowledge of its occurrence.
Id. at 406-407, 67 S.Ct. at 781 (footnote omitted). Following United Brotherhood of Carpenters, Congress provided a right of action for money damages in certain labor disputes in Section 303(b) of the Labor Management Relations Act, 29 U.S.C. § 187(b) (1982).5 In United Mine Workers v. Gibbs, 383 U.S. 715, 86 S.Ct. 1130, 16 L.Ed.2d 218 (1966), the Court compared Section 303(b) of the Labor Management Relations Act with Section 6 of the Norris-LaGuardia Act and stated that “the responsibility of a union for the acts of its members and officers [under § 303] is to be measured by reference to ordinary doctrines of agency, [523]*523rather than the more stringent standards of § 6 [of the Norris-LaGuardia Act].” Id. at 736, 86 S.Ct. at 1144. Thus, it is clear that both Section 6 of the Norris-LaGuardia Act and Section 8 of the Pennsylvania Anti-Injunction Act require a higher showing than the common law rules of agency. See Dow Chemical Co. v. International Union of Elec., Radio & Mach. Workers, 480 F.2d 433, 437 (5th Cir.1973), cert. denied, 415 U.S. 932, 94 S.Ct. 1444, 39 L.Ed.2d 490 (1974); Note, Union Responsibility for Acts of Officers and Members, 63 Harv.L.Rev. 1035, 1039 (1950).6
In an effort to avoid the difficult proof requirements of Section 8, appellants proffer two arguments, neither of which is persuasive. First, appellants contend, and Common Pleas agreed, that the legislature, through the adoption of Section 8, did not intend to supplant common law agency principles in personal injury matters. They argue that the statute was designed to protect unions solely from suits for economic damages stemming from a labor dispute.
We do not agree. Protecting unions from damage awards which would impinge upon the collective rights of workers is the clear import of Section 8. Supra at 855. The protection is available regardless of the theory that the plaintiff pursues. The purpose of this section’s higher standard of proof in civil actions is the protection of the worker’s right to collective bargaining without exposing his union to the higher costs engendered by the agency notion of respondeat superior. Since the union generally has no pool of profits with which to withstand the impact of unanticipated and costly damage awards, it could well be destroyed by an inadequately established claim.
[524]*524Second, appellants argue that Section 4 of the act serves to remove all acts of violence from the strictures of the Anti-Injunction Act. Since their cause of action is predicated upon a series of violent acts, they contend, the unique proof requirements of Section 8 do not apply. Section 4(d) of the act states:
No court of this Commonwealth shall have jurisdiction to issue any restraining order or temporary or permanent injunction in a case included within this act, except in strict conformity with the provisions of this act, nor shall any such restraining order or temporary or permanent injunction be issued contrary to the public policy declared in this act. Exclusive jurisdiction and power to hear and determine all actions and suits coming under the provisions of this act, shall be vested in the courts of common pleas of the several counties of this Commonwealth: Provided, however, That this act shall not apply in any case—
(d) Where in the course of a labor dispute as herein defined, an employe, or employes acting in concert, or a labor organization, or the members, officers, agents, or representatives of a labor organization or anyone acting for such organization, seize, hold, damage, or destroy the plant, equipment, machinery, or other property of the employer with the intention of compelling the employer to accede to any demands, conditions, or terms of employment, or for collective bargaining.
43 P.S. § 206d(d). Appellants argue that the language “this act shall not apply in any case,” coupled with the prohibition against violence in Section 4(d), 43 P.S. § 206d(d), prevents the use of Section 8 of the Act in cases involving violent acts. Careful scrutiny of Section 4, 43 P.S. § 206d, reveals that subsections (a) through (d) were added to the Act of June 2, 1937, P.L. 1198, No. 308, by the Act of June 9, 1939, P.L. 302, No. 163. Prior to that amendment, Section 4 concluded with the word “Commonwealth” immediately before the proviso. Subsection (d) was [525]*525added to restore to a chancellor the power to enjoin a violent labor dispute. The subsection does not abrogate the protections afforded in Section 8 which apply to any organization or association “in any civil action at law or suit in equity.” Anti-Injunction Act, supra, § 8, 43 P.S. § 206h. It does not apply to actions at law for damages. An injunction poses no threat to the viability of a labor organization whereas damage awards may quickly strangle the entity responsible for bargaining on behalf of workers. Hence, in amending the original act in 1939, the legislature retained the original higher standard of proof for damage actions. The 1939 amendment was intended to insure that an injunction will quickly issue when required to calm a heated and violent labor dispute. Link Belt Co. v. Local 118 American Federation of Technical Eng’rs, 415 Pa. 122, 202 A.2d 314 (1964). Regarding the limited impact of the 1939 amendments, we stated in Link Belt:
Section 4, as originally drafted, deprived our courts of jurisdiction to grant injunctions in labor disputes except as provided elsewhere in the Act. The proper and logical section for amendment to create exceptions to that limitation of jurisdiction is Section 4. The balance of the Act remains in full effect in those situations covered by the jurisdictional section.
Link Belt, supra, 415 Pa. at 128, 202 A.2d at 317 (emphasis added).
This distinction is also sound from the standpoint of policy. A union qua union can have no legitimate interest in preventing an injunction against violence on the picket line, whether or not it participated in fomenting that violence. If it did, it is properly a party. If it did not, it should support an end to the violence as all good citizens are required to do. On the other hand, a civil suit for damages against a union which did not participate or foment unlawful acts by its members can destroy or severely cripple a union which has taken no part in its members’ unlawful acts. Therefore, to permit such suits without proof of actual participation strikes at the core of the act’s [526]*526policy of protecting unions as entities from adverse consequences arising from acts in which they did not participate. With these general principles in mind, we now turn to the facts of the case sub judice.
II. PARTICIPATION OF LOCAL 107
For a labor organization to be liable for “participation” pursuant to Section 8 of the Anti-Injunction Act, a jury must find that (1) the acts were committed by officers, members or agents of the organization and (2) the organization actually participated in the acts. Such a finding must be predicated upon clear proof. Philadelphia Marine, supra at 453 Pa. 52, 308 A.2d at 103 (quoting Gibbs, supra). It is beyond question that the major players in this tragedy were members of Local 107. The difficult question is whether the entity itself, Local 107, “participated” in the drama and so is liable to compensate the victims. A finding of participation may be based upon circumstantial evidence. Ritchie v. United Mine Workers, 410 F.2d 827, 833 (6th Cir.1969). See also James R. Snyder Co. v. Edward Rose & Sons, 546 F.2d 206, 209 (6th Cir.1976) (proof of authorization or ratification can be based upon circumstantial evidence). In determining whether a labor organization has actually participated in the commission of an act, we hold that the number of persons involved, the status of these persons in the organization, and whether the organization was aware of and in a position to exercise control over the acts, are all relevant considerations. See United Aircraft Corp. v. International Association of Machinists, 161 Conn. 79, 89, 285 A.2d 330, 337 (1971), cert. denied, 404 U.S. 1016, 92 S.Ct. 675, 30 L.Ed.2d 663 (1972). This record shows clear proof of Local 107’s participation in the sorrowful events of January 25, 1980, a participation for which it should be condemned and held accountable to those injured. Therefore, Superior Court erred in granting judgment n.o.v. in favor of the appellee, Local 107.
At this point, an exacting review of the 1,113 page trial transcript is necessary. The following people were primary [527]*527participants in this tragedy. At the time of the strike and shooting, Joseph Cimino was president of Local 107. John Smalley was a business agent/recording secretary of the Local and chief negotiator in the ongoing discussions with 3M. Mr. Smalley was, according to his own testimony, responsible for control of the picket line. N.T. February 28, 1984 at 371. William Crossan was an employee of 3M, the local union’s chief steward and a member of its negotiating committee. Robert Kendig was a union steward and employee at the Bristol plant and also a member of the negotiating committee. Robert Ballinger was an employee of 3M, a member of Local 107 and the individual who fired the pistol, injuring fellow picketers Gajkowski and Schipske and 3M security guard Abate.
Although pulling the trigger was the physical act of one intoxicated picketer, there is sufficient evidence from which the jury could properly hold that Local 107 participated in the calamity of January 25. On that fateful day, Crossan, Kendig, Ballinger and two others went to the “Tulleytown Tank” for lunch. Crossan stated that the men “drank continuously” for a couple of hours. Id. at 424. Upon their return to the line, Crossan and Kendig began handing out leaflets to non-striking employees. Id. at 425. 3M security supervisor Joseph Boxmeyer asked Crossan and Kendig to stop doing this on 3M’s property. N.T. February 29, 1984 at 79-81. Kendig went on to let air out of the tires of cars on the 3M lot. N.T. February 28, 1984 at 429; February 29, 1984 at 81. Later, Crossan and Kendig left in Kendig’s truck, ostensibly to check on Kendig’s children. Before leaving, a striker overheard Kendig remark that he was going to get a gun to shoot out 3M’s lights and security camera. N.T. February 28, 1984 at 195. At Kendig’s house, both Crossan and Kendig had a shot of alcohol before coming back to the line. While they were riding back to the plant, Kendig showed Crossan a gun he was storing in the truck. Crossan made no objection to Ken-dig’s bringing the gun on the line. N.T. February 28, 1984 at 432-434.
[528]*528Kendig took the gun into the strike trailer across the street from 3M’s property. Strikers were assembled in the trailer playing cards. Kendig displayed the gun to all present and exclaimed “deal me in.” N.T. February 27, 1984 at 121. At this, Kendig laughed and left the trailer. Id. at 122. The record is filled with evidence that large amounts of alcohol were consumed on the line that evening. Id. at 110, 113, 115; February 28, 1984 at 175,177. Balling-er, who would later fire the injurious shots, was described by a number of witnesses as drunk. N.T. February 27, 1984 at 118; February 28, 1984 at 182. Soon, rocks and bottles were being thrown at the plant. N.T. February 27, 1984 at 126. Two witnesses credited Kendig with throwing the first bottle and shouting, “This will get something started.” Id.; N.T. February 28, 1984 at 292. George Cook, the picket line captain, testified that he had been drinking and took part in throwing the rocks and bottles. N.T. February 28, 1984 at 275-76. One bottle went astray and hit Ballinger on the head. N.T. February 27, 1984 at 128; February 28, 1984 at 252.
The once peaceful picket line deteriorated into a raucous mob. One witness described the growing tension and two witnesses characterized the situation as “rowdy.” N.T. February 27, 1984 at 130; February 28, 1984 at 190. Joseph Boxmeyer, 3M’s security head, noted in his log that the picketers were attempting to create a confrontation through their actions. N.T. February 29, 1984 at 85; Plaintiffs’ Exhibit No. 59. Some time after 7:00 P.M., one picketer and an employee of 3M reported shots. N.T. February 27, 1984 at 134; Plaintiffs’ Exhibit No. 36. Crossan then met Kendig near the gas station across the street from the plant; Kendig handed Crossan the pistol and urged Crossan to shoot out the lights at the plant. Crossan replied, “I don’t know how.” Kendig offered to instruct him; Crossan decided to go to the men’s room. N.T. February 28, 1984 at 434-35. He admitted that he did not attempt to restrain Kendig or contact Smalley. Id. at 436. After Crossan departed, Kendig met up with Ballinger and [529]*529Ballinger fired the shots from Kendig’s gun which injured appellants.
Jack Smalley, business agent for Local 107, testified that he was responsible for the conduct of the strike at the Bristol 3M plant. N.T. February 28, 1984 at 371. He asserted that Local 107 had a rule against drinking alcoholic beverages on the picket line. Id. at 376, 379. At least four witnesses testified there was no such rule. N.T. February 27, 1984 at 110; February 28, 1984 at 236, 241, 273. Smalley stated that he was aware of drinking on the line but admitted he took no steps to curb it. Id. at 388-390. George Cook testified that on one occasion he observed George Massimini, another business agent of Local 107, delivering alcoholic beverages to the strikers. Id. at 279-80.
This record reveals a dangerous combination of escalating tensions, alcohol and firearms. The firing of the pistol at the three victims was not the act of a lone perpetrator but the end result of a collective assault on the 3M plant. The passing of the weapon among union officials responsible for the negotiating process is sufficient to hold Local 107 liable as a participant. See, e.g., Charles D. Bonanno Linen Service v. McCarthy, 708 F.2d 1, 11-12 (1st Cir.1983) (imposition of liability on union where union representative, vested with authority to control violence, failed to act), cert. denied, 464 U.S. 936, 104 S.Ct. 346, 78 L.Ed.2d 312 (1983). See also NLRB v. Brewery and Beer Distrib. Drivers, 281 F.2d 319, 321-22 (3d Cir.1960) (court deems authority of stewards comparable to that of factory foremen); Evans, The Law of Agency and the National Union, 49 Ky.L.J. 295, 314 (1961) (discusses authority of stewards as bottom link in chain of union command). The record shows that many strikers, with varying degrees of authority, were aware of the pistol on the line.7 No one used his authority [530]*530to remove it or stop the drinking. Business agent Smalley’s failure to do anything is not only a failure of personal responsibility but a failure by the union which gave him that responsibility. From it, the jury could properly infer the “knowing tolerance” of violence held actionable under the Norris-LaGuardia Act by the United States Supreme Court in Gibbs, supra 383 U.S. at 739, 86 S.Ct. at 1145-46. Knowing tolerance finds no greater excuse in Pennsylvania. Our legislature did not intend Section 8 of the Pennsylvania Labor Anti-Injunction Act to countenance total abdication of union responsibility for deadly violence in tense labor situations. There is a time when those who have accepted responsibility from their fellow workers for advancing the collective good cannot look the other way while irresponsible men openly foment violence which injures people and hauls the labor movement into disrepute.
This record also includes circumstantial evidence that Joseph Cimino, president of Local 107, sanctioned the assault on the Bristol plant. Three days prior to the events of January 25, Cimino attended a meeting at the Washington, D.C. office of the IBT to discuss a number of unresolved issues. Present were Cimino, Norman Weintraub, an IBT economist, Joseph Cotter, an IBT staff employee, Nelson Schmidt, a 3M attorney, and Robert Hanson, a 3M personnel manager. At the conclusion of the meeting, Cimino and Hanson agreed to re-evaluate their positions during a follow-up phone call. Mr. Hanson’s notes, introduced into evidence by stipulation, reveal the content of his conversation with Cimino on January 25, the day of the melee:
Joe Cimino called me answering my call to Cotter. Summary of conversation: We need all 13 items I gave you yesterday. People are adamant and strong. I’ve spent a lot of time on picket line. They won’t go back to work for a few cents. I’ve got to represent them. We’re going to extend our picketing. I’ve got approval from the Inti. We’re going to do what we have to do — it’s [531]*531been peaceful for ten weeks — it’s getting hot now — they are uptight — we’ve got to get mgmt’s attention. I have no malice — I won’t lie to you or sandbag you. These people don’t like being 2nd class citizens — they compare rates and benefits with St. Paul, and other three plants & don’t like being behind. Everybody has sick days these days. You get injunction & then tell us where you’re shipping all boxcars — it’s written on cars “To Anchor” or “To Leño” — that’s really rubbing salt in wounds. First time they’re doing it. We’re have a demonstration Mon. in Phil. — 95% of 3M will be there and some truck drivers.
Plaintiff’s Exhibit No. 28 (emphasis added).8 The appellees contend that Mr. Cimino’s statement refers to legitimate efforts to extend the picketing to other 3M facilities and a rally to be held in Philadelphia to demonstrate support for Local 107. Whether Cimino’s comments refer to the violence of January 25 or to the proposed legitimate efforts to pressure 3M was for the jury to decide.
Because Common Pleas properly instructed the jury on the applicability of the Labor Anti-Injunction Act through the use of special interrogatories, our review is limited to a determination of whether there is sufficient evidence on which to base the jury’s verdict. Burbage v. Boiler Eng’g. & Supply Co., 433 Pa. 319, 323, 249 A.2d 563, 566 (1969). Our system vests the responsibility of determining the facts with the jury and we will not upset their findings absent a showing that the verdict is capricious, against the weight of the evidence and resulted in a miscarriage of justice. Simon v. H.K. Porter Co., 407 Pa. 359, 363, 180 A.2d 227, 229 (1962). We are particularly reluctant to disturb a verdict which is supported by both the trial court and a panel of that court sitting en banc. Skoda v. West Penn Power Co., 411 Pa. 323, 338, 191 A.2d 822, 830 [532]*532(1963); Roadman v. Bellone, 379 Pa. 483, 491, 108 A.2d 754, 758 (1954).
Our detailed factual recital shows that there is evidence on this record sufficient for a jury to determine that enough of the membership of Local 107 and of its officers took part in the tragic events of January 25 to hold the Local liable as a participant for the appellants’ damages. The principal players include stewards serving as agents on the negotiating committee, officers and a host of members of the Local. The record bespeaks rising tensions, fueled by alcoholic beverages, that reached a violent crescendo on the evening of January 25, without any responsible effort to avert it. Considering the evidence which the jury had when it held Local 107 liable, we see no reason to disturb that verdict.
III. PARTICIPATION OF THE IBT
While the record is full of evidence from which the jury properly inferred the participation of Local 107 in the January 25 violence, there is no clear proof of either actual participation or actual authorization by the IBT. At trial, appellants sought to demonstrate, through the introduction of copies of the constitutions of the two organizations, that the local is the agent of the parent and therefore jointly liable for the harm. This effort to demonstrate an agency relationship was buttressed by evidence of strike benefits paid from the IBT to local members. Also, appellants proffered evidence of a parade held in Philadelphia three days after the shooting; however, there was absolutely no showing that the officers of the IBT sanctioned this event as a demonstration of support of the violence of January 25. This showing falls well short of the clear proof of actual authorization or actual participation called for in Section 8. Cf. Riverside Coal Co. v. United Mine Workers, 410 F.2d 267 (6th Cir.1969) (parent union’s agents actually involved in violence), cert. denied, 396 U.S. 846, 90 S.Ct. 89, 24 L.Ed.2d 95 (1969). Indeed, this is precisely the situation in which the legislature intended to protect a union from the imposition of liability through its enactment of Section 8. [533]*533Appellants’ evidence could demonstrate a common law agency relationship. This is insufficient under the statute. While fears of strangling new unions may seem to have little relevance in the context of today’s large and powerful national bodies, a change from participation to respondeat superior as the basis for union liability is a decision for the legislature, not the courts.
The day-to-day functions of a labor organization will not evidence liability for tortious conduct. For example, a number of courts have held that the payment of routine strike benefits alone does not give rise to liability under Section 6 of the Norris-LaGuardia Act. Gibbs, supra 383 U.S. at 738, 86 S.Ct. at 1145; Federal Prescription Serv. v. Amalgamated Meat Cutters, 527 F.2d 269, 276-77 (8th Cir.1975). Absent a showing that the IBT took affirmative steps to either sanction or take part in the events of January 25, Superior Court properly exonerated the organization from any liability.
Based on the foregoing, the order of Superior Court is reversed with regard to Local 107. It is otherwise affirmed.
