tary petition in bankruptcy under Chapter 11 of the Bankruptcy Code, 11 U.S.C. § 101 et seq., (the “Code”), on December 12,1983. The trustee claims that the payment to Texaco is a voidable preferential transfer under 11 U.S.C. § 547(b). Texaco denies the allegation and asserts the payment falls within the § 547(c)(2) exception to avoidability.
A motion for summary judgment permits consideration of only whether “there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law.” Rule 56(c) F.R.C.P. (1984). The moving party has the burden of demonstrating the absence of any genuine issues of material fact which precludes such relief. Quinn v. Syracuse Model Neighborhood Corp., 613 F.2d 438, 445 (2d Cir.1980); In re Euro-Swiss International Corp., 33 B.R. 872, 878 (Bankr.S.D.N.Y.1983). But where there is no genuine dispute as to a material fact, summary judgment has an appropriate and necessary role in efficient dispute resolution. The opposing party, therefore, cannot defeat such a demonstration through surmise, conjecture or allegation; it must come forward with facts asserted on the basis of knowledge rather than rest on an attorney’s affidavit. Quinn, 613 F.2d at 445; Applegate v. Top Associates, 425 F.2d 92, 96 (2d Cir.1979); Dressler v. MV Sandpiper, 331 F.2d 130, 133-33 (2d Cir.1964).
A trustee may only avoid a transfer if it both meets the requirements of § 547(b) of the Code and does not fall within one of the exceptions provided by § 547(c). There is no dispute that Hellenic’s payment to Texaco was “to or for the benefit of the creditor,” § 547(b)(1), and that it was on the account of an antecedent debt incurred on the delivery of bunker fuel. See § 547(b)(2). Moreover, the honoring of Hellenic’s check by the drawee bank on October 6 was within the 90-day period before the filing of the petition. See § 547(b)(4). Insolvency, the fourth element, is presumed. See § 547(f).
Section 547(b), however, is not satisfied unless the payment
that enables such creditor to receive more than such creditor would receive if
(A) the case were under Chapter 7 of this title;
(B) the transfer had not been made; and
(C) such creditor received payment of such debt to the extent provided by the provisions of this title.
Here, Texaco acquired a maritime lien on the M/V Hellenic Sun on its physical delivery of necessaries (bunker fuel) to Hellenic’s vessel. Riffe Petroleum Co. v. Cibro Sales Corp., 601 F.2d 1385, 1389 (10th Cir.1979); § 506(a); 46 U.S.C. § 971, et seq. It, therefore, contends that the payment discharged its maritime lien and, consequently, it did not receive more than it would in liquidation. For the same reason, it contends that the transaction falls within the exception codified in § 547(c)(1). That section provides that a transfer may not be avoided if such transfer was:
(A) intended by the debtor and the creditor to or for whose benefit such transfer was made to be a contemporaneous exchange for new value given to the debtor; and
(B) in fact a substantially contemporaneous exchange.
§ 547(c)(1).
Maritime liens, however, are accorded inverse priority; within ordered priorities, the last in time is first in right. Gilmore and Black, The Law of Admiralty at §§ 9-22, 9-23 (2d ed. 1975). The trustee’s counsel, at the argument, claimed, apparently on the basis of having examined public court documents, that upon the libel of the vessel before the United States District Court for the District of Maryland, approximately $4,000,000 was realized and that some $30,000,000 in maritime liens have been asserted against it. These averments raise an issue of fact as to the value of Texaco’s lien, thereby precluding summary judgment.
Because of that factual dispute, resolution of Texaco’s summary judgment therefore turns on the exemption provided by § 547(c)(2) as it stood prior to amendment
