delivered the opinion of the Court.
The question in this case is whether the Circuit Court of Appeals was in error in holding that a debtor’s petition filed by petitioner under Ch. X of the Bankruptcy Act (52 Stat. 883, 11 U. S. C. § 501) was not filed in “good faith.”
The debtor’s sole asset is an apartment building in New York City which is subject to a first mortgage of $370,000. This mortgage is held by the respondent, Manufacturers Trust Co. (successor to The Mortgage Corporation of New York), as trustee for certificate holders. There are also junior mortgages and other claims, including an unspecified amount of unsecured indebtedness. Concededly the property of the debtor is worth less than the amount of the first mortgage debt. The first mortgage was originally created in 1931 and was held by Title Guarantee and Trust Co., which issued and sold to the public certificates of participation, guaranteed as to principal and interest by Bond and Mortgage Guarantee Co. The latter company became involved in financial difficulties in 1933 and was taken over by the Superintendent of Insurance of New York for rehabilitation. 1 Pursuant to provisions of the Schackno Act (N. Y. Laws 1933, c. 745), the Superin-, tendent of Insurance promulgated, in 1934, a plan for the readjustment of the rights of the certificate holders in the mortgage, by which the mortgage was extended to December 1, 1937 and the interest reduced. Over two-thirds of the certificate holders consented to the plan, and the debtor j oined in the extension agreement. The New York court approved it. In 1935 the New York Mortgage Commission succeeded the Superintendent of Insurance as administrator of certificated bonds and mortgages. *82 N. Y. Laws 1935, c. 19, c. 290. That Commission, 2 in 1938, proposed the designation of the Mortgage Corporation of New York as trustee of the bond and mortgage in the instant case, under a declaration of trust granting the trustee broad and comprehensive powers. This proposal was consented to by over two-thirds of the certificate holders and approved by the New York court. The order of the court provided “that this Court, having assumed jurisdiction of this proceeding, shall retain jurisdiction hereof until the complete liquidation of the Trust Estate and the termination of the trust; and the Trustee, or any other interested party herein, may apply at the foot of this Final Order upon such notice as the Court may direct for such other and further relief as to the Court may seem just and proper.”
The principal of the first mortgage was not paid at its extended maturity in 1937. But until April 1, 1941, the debtor made all other payments due under the 1934 extension agreement. At that time the debtor defaulted in payment of interest and taxes. Both before and after that default the debtor and the trustee negotiated for an agreement of further extension and modification. But no agreement between them could be reached and no further proposal for a modification or extension of the mortgage was presented to the state court or to the certificate holders. On May 1,1941, the trustee instituted foreclosure proceedings in the state court. A receiver was appointed, who took possession. In September 1941 the debtor filed its voluntary petition under Ch. X of the Bankruptcy Act. An
ex parte
order approving the petition and appointing trustees was obtained. Shortly thereafter the mortgage trustee moved to vacate that order and to dismiss the debtor’s petition on the ground that it was not filed in
*83
“good faith.” That motion was denied.
Every petition under Ch. X must state, inter alia, “the specific facts showing the need for relief under this chapter.” § 130 (7). Sec. 141 provides that the judge shall enter an order approving a debtor’s petition “if satisfied that it complies with the requirements of this chapter and has been filed in good faith, or dismissing it if not so satisfied.” Sec. 146 defines “good faith” and provides in part:
“Without limiting the generality of the meaning of the term 'good faith’, a petition shall be deemed not to be filed in good faith if—
“(4) a prior proceeding is pending in any court and it appears that the interests of creditors and stockholders would be best subserved in such prior proceeding.”
The federal bankruptcy power is, of course, paramount and supreme and may be so exercised by Congress as to exclude every competing or conflicting proceeding in state or federal tribunals.
Kalb
v.
Feuerstein,
In view of that history, it seems clear that, when a prior proceeding is pending, a petitioner’s showing of “need for relief” under Ch. X, required to be contained in every petition by the express provisions of § 130 (7), must demonstrate that at least in some substantial particular the prior proceedings withhold or deny creditors or stockholders benefits, advantages, or protection which Ch. X affords. In absence of such a showing, the “need for relief” has not been established and the District Court is not enabled to make an informed judgment on the “good faith” issue.

v.
Rembaugh,
We are of the opinion, however, that the debtor did not sustain the burden which the federal statute places on a petitioner. So far as the “interests” of stockholders are concerned, it is not apparent that the equity owners would be denied in the state foreclosure proceedings benefits, advantages, or protection which Ch. X would afford them. Admittedly the property is worth less than the amount of the first mortgage indebtedness. Under the rule of

v.
Boyd,
The District Court, however, concluded that it was in the interests of all the creditors that the Ch. X petition be approved. It noted that the market value of the certificates was far under par and that there were lienors and creditors, other than the first mortgage certificate holders, with which the bankruptcy court, but not the state court, could deal. If there were a showing, for example, that the property was worth more than the amount of first mortgage indebtedness and it appeared that that excess value would be lost to the junior interests in the state proceedings, or that the state proceedings were less adequate by reorganization standards than the bankruptcy court to protect such interests, approval of the petition clearly would be justified whether filed by the debtor or by creditors. But no such showing was made. Hence it was not established that continuation of the state proceedings would deny the junior creditors any benefits which Ch. X would afford them. Approval of the petition on the grounds advanced by the District Court could be made only under the composition theory of reorganization, which Ch. X, like § 77B, rejected in favor of the full priority rule of the

There remains the contention that it was in the “interests” of the certificate holders to have the proceedings transferred to Ch. X. In this connection, much emphasis is placed on numerous safeguards contained in Ch. X, which this Court reviewed in
