71 Pa. Stat. § 1707.6
The rights and the remedies, herein conferred upon or granted to the bondholders, shall be in addition to and not in limitation of any rights and remedies lawfully granted to such bondholders by the resolution or resolutions providing for the issuance of bonds, or by any deed of trust, indenture or other agreement under which the same may be issued. In the event that the Authority shall default in the payment of principal of or interest on any of the bonds after said principal or interest shall become due, whether at maturity or upon call for redemption, and such default shall continue for a period of thirty (30) days, or in the event that the Authority shall fail or refuse to comply with the provisions of this act, or shall default in any agreement made with the holders of the bonds, the holders of twenty-five per centum (25%) in aggregate principal amount of the bonds then outstanding, by instrument or instruments filed in the office of the recorder of deeds of the county, and proved or acknowledged in the same manner as a deed to be recorded, may (except as such right may be limited under the provisions of any deed of trust, indenture or other agreement as aforesaid) appoint a trustee to represent the bondholders for the purposes herein provided. Such trustee and any trustee under any deed of trust, indenture or other agreement may, and, upon written request of the holders of twenty-five per centum (25%) (or such other percentage as may be specified in any deed of trust, indenture or other agreement aforesaid) in principal amount of the bonds then outstanding, shall in his or its own name--
Any trustee, whether appointed as aforesaid or acting under a deed of trust, indenture or other agreement and whether or not all bonds have been declared due and payable, shall be entitled as of right to the appointment of a receiver, who may (to the same extent that the Authority itself could so do) enter and take possession of the facilities of the Authority, or any parts thereof, the revenues, rentals, or receipts from which are or may be applicable to the payment of the bonds so in default, and operate and maintain the same, and collect and receive all rentals and other revenues thereafter arising therefrom in the same manner as the Authority might do, and shall deposit all such moneys in a separate account, and apply the same in such manner as the court shall direct. In any suit, action or proceeding by the trustees, the fees, counsel fees, and expenses of the trustee and of the receiver, if any, and all costs and disbursements allowed by the court, shall be a first charge on any revenues and receipts derived from the facilities of the Authority, the revenues or receipts from which are or may be applicable to the payment of the bonds so in default. Said trustee shall, in addition to the foregoing, have and possess all of the powers necessary or appropriate for the exercise of any functions specifically set forth herein or incident to the general representation of the bondholders in the enforcement and protection of their rights.
In addition to all other rights and all other remedies, any holder of bonds of the Authority shall have the right by mandamus or other suit, action, or proceeding at law or in equity to enforce his rights against the Authority, including the right to require the Authority to collect fees, rentals, and other charges adequate to carry out any agreement as to or pledge of such fees, rentals, or other charges, or income revenues and receipts, and to require the Authority to carry out any of its covenants and agreements with the bondholders, and to perform its and their duties under this act: Provided, however, That nothing in this section or any other section of this act shall authorize any receiver appointed pursuant to this act, for the purpose of operating and maintaining any facilities of the Authority, to sell, assign, mortgage, or otherwise dispose of, any of the assets of whatever kind and character belonging to the Authority. It is the intention of this act to limit the powers of such receiver to the operation and maintenance of the facilities of the Authority as the court shall direct, and no holder of bonds of the Authority, nor any trustee, shall ever have the right in any suit, action or proceedings at law or in equity to compel a receiver, nor shall any receiver ever be authorized, or any court be empowered to direct the receiver, to sell, assign, mortgage, or otherwise dispose of, any assets of whatever kind or character belonging to the Authority.
