Pennsylvania constitution
Article III: legislation
Section 18

The General Assembly may enact laws requiring the payment by employers, or employers and employees jointly, of reasonable compensation for injuries to employees arising in the course of their employment, and for occupational diseases of employees, whether or not such injuries or diseases result in death, and regardless of fault of employer or employee, and fixing the basis of ascertainment of such compensation and the maximum and minimum limits thereof, and providing special or general remedies for the collection thereof; but in no other cases shall the General Assembly limit the amount to be recovered for injuries resulting in death, or for injuries to persons or property, and in case of death from such injuries, the right of action shall survive, and the General Assembly shall prescribe for whose benefit such actions shall be prosecuted. No act shall prescribe any limitations of time within which suits may be brought against corporations for injuries to persons or property, or for other causes different from those fixed by general laws regulating actions against natural persons, and such acts now existing are avoided.
