There's no FEDERAL common law because the US gov't is BANKRUPT. And it is bankrupt because it delegated issuance of currency to private bankers, the Federal Reserve, in 1933. Which means that all the assets in the US Treasury are to be FIRST used to pay off the federal debt, so they CAN'T be issued into circulation in form of silver and gold coins UNTIL that debt is paid off.

"On April 25, 1938, the Supreme Court overturned the standing precedents of the prior 150 years concerning “common law,” in the Federal Government.“THERE IS NO FEDERAL COMMON LAW, AND CONGRESS HAS NO POWER TO DECLARE SUBSTANTIVE RULES OF COMMON LAW APPLICABLE IN A STATE, WHETHER THEY BE LOCAL OR GENERAL IN THEIR NATURE, BE THEY COMMERCIAL LAW OR A PART OF THE LAW OF TORTS” (See: Erie Railroad Co. Vs. Tompkins, 304 U.S. 64, 82 L.Ed. 1188).
The Common Law is the fountain source of Substantive and Remedial Rights, if not our very Liberties (See: Stephen, A Treaties On The Principles Of Pleading, Introduction, Pg. 23; Hemmingway, History Of Common Law Pleading As Evidence Of The Growth Of Individual Liberty And Power Of The Courts, 5 Alabama Law Journal 1; Swift vs. Tyson, 16 Peters 1, 10 L.Ed. 865; Constitution, Article III, Section 2, Amendments VII, IX and X.)
The members and association of the Bar thereafter formed committees, granted themselves special privileges, immunities and franchises, and held meetings concerning the Judicial procedures, and further, to amend laws “to conform to a trend of judicial decisions or to accomplish similar objectives”, including hodgepodging the jurisdictions of Law and Equity together, which is known today as “One Form Of Action.” (See: Constitution And By Laws, Article 3, Section 3.3(c), 1990-91 Reference Book, supra, see also, Colorado Methods of Practice, West Pub., Vol. 4, pgs. 2-3, Authors Comments.)

NOTE: The enumerated, specified and distinct Jurisdictions established by the ordained Constitution (1789), Article III, Section 2, and under the Bill of Rights (1791), Amendment VII, were further hodgpodged and fundamentally changed in 1982 to include Admiralty Jurisdiction, which was once again brought inland.

“This is the FUNDAMENTAL CHANGE necessary to effect unification of CIVIL and ADMIRALTY PROCEDURE. Just as the 1938 Rules ABOLISHED THE DISTINCTION between ACTIONS AT LAW and SUITS IN EQUITY, this change would ABOLISH THE DISTINCTION between CIVIL ACTIONS and SUITS IN ADMIRALTY.” (Federal Rules Of Civil Procedure, 1982 Ed., pg. 17, also see, Federalist Papers No. 83; Declaration Of Resolves Of The First Continental Congress; Oct. 14, 1774, Declaration Of Cause And Necessity Of Taking Up Arms; July 6, 1775, Declaration of Independence; July 4, 1776, Bennet vs. Butterworth, 52 U.S. 669.)"
