18 Pa.C.S.A. §307.  Liability of organizations and certain related persons.

(a)  Corporations generally.–A corporation may be convicted of the commission of an offense if:

(1)  the offense is a summary offense or the offense is defined by a statute other than this title in which a legislative purpose to impose liability on corporations plainly appears and the conduct is performed by an agent of the corporation acting in behalf of the corporation within the scope of his office or employment, except that if the law defining the offense designates the agents for whose conduct the corporation is accountable or the circumstances under which it is accountable, such provisions shall apply;

(2)  the offense consists of an omission to discharge a specific duty of affirmative performance imposed on corporations by law; or

(3)  the commission of the offense was authorized, requested, commanded, performed or recklessly tolerated by the board of directors or by a high managerial agent acting in behalf of the corporation within the scope of his office or employment.

(b)  Corporations, absolute liability.–When absolute liability is imposed for the commission of an offense, a legislative purpose to impose liability on a corporation shall be assumed, unless the contrary plainly appears.

(c)  Unincorporated associations.–An unincorporated association may be convicted of the commission of an offense if:

(1)  the offense is defined by a statute other than this title which expressly provides for the liability of such an association and the conduct is performed by an agent of the association acting in behalf of the association within the scope of his office or employment, except that if the law defining the offense designates the agents for whose conduct the association is accountable or the circumstances under which it is accountable, such provisions shall apply; or

(2)  the offense consists of an omission to discharge a specific duty of affirmative performance imposed on associations by law.

(d)  Defenses.–In any prosecution of a corporation or an unincorporated association for the commission of an offense included within the terms of paragraph (a)(1) or paragraph (c)(1) of this section, other than an offense for which absolute liability has been imposed, it shall be a defense if the defendant proves by a preponderance of evidence that the high managerial agent having supervisory responsibility over the subject matter of the offense employed due diligence to prevent its commission. This subsection shall not apply if it is plainly inconsistent with the legislative purpose in defining the particular offense.

(e)  Persons acting or under a duty to act for organizations.–

(1)  A person is legally accountable for any conduct he performs or causes to be performed in the name of a corporation or an unincorporated association or in its behalf to the same extent as if it were performed in his own name or behalf.

(2)  Whenever a duty to act is imposed by law upon a corporation or an unincorporated association, any agent of the corporation or association having primary responsibility for the discharge of the duty is legally accountable for a reckless omission to perform the required act to the same extent as if the duty were imposed by law directly upon himself.

(3)  When a person is convicted of an offense by reason of his legal accountability for the conduct of a corporation or an unincorporated association, he is subject to the sentence authorized by law when a natural person is convicted of an offense of the grade and the degree involved.

(f)  Definitions.–As used in this section the following words and phrases shall have the meanings given to them in this subsection:

“Agent.”  Any director, officer, servant, employee or other person authorized to act in behalf of the corporation or association and, in the case of an unincorporated association, a member of such association.

“High managerial agent.”  An officer of a corporation or an unincorporated association, or, in the case of a partnership, a partner, or any other agent of a corporation or association having duties of such responsibility that his conduct may fairly be assumed to represent the policy of the corporation or association.
