28 U.S. Code § 1925 - Admiralty and maritime cases

Except as otherwise provided by Act of Congress, the allowance and taxation of costs in admiralty and maritime cases shall be prescribed by rules promulgated by the Supreme Court.

(June 25, 1948, ch. 646, 62 Stat. 957.)
Historical and Revision Notes

This section was drafted to make possible the promulgation of comprehensive and uniform rules governing costs in admiralty. Various enactments of Congress, all over 100 years old, relate to particular features of such matter, but do not set forth any comprehensive and uniform procedure. See, for example, sections 818, 826, and 827 of title 28, U.S.C., 1940 ed.
