According to the
Supremacy Clause (Article VI, clause 2) of the
United States Constitution, This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the Supreme law of the land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding. As the Supreme Court stated in
Altria Group v. Good, 555 U.S. 70 (2008), a federal law that conflicts with a state law will overtake, or "preempt", that state law: Consistent with that command, we have long recognized that state laws that conflict with federal law are "without effect".
Maryland v. Louisiana, 451 U. S. 725, 746 (1981) Although many
concurrent powers are subject to federal preemption, some are usually not, such as the power to tax private citizens.
Intent of Congress presumed to be deference to states In
Altria Group v. Good, 555 U.S. 70 (2008), the Court wrote: When the text of a pre-emption clause is susceptible of more than one plausible reading, courts ordinarily "accept the reading that disfavors pre-emption.
Bates v. Dow Agrosciences LLC, 544 U.S. 431, 449 (2005). In
Wyeth v. Levine, (2009), the Court emphasized what it called the "two cornerstones" of pre-emption jurisprudence: First, "the purpose of Congress is the ultimate touchstone in every pre-emption case".
Medtronic, Inc. v. Lohr, 518 U. S. 470, 485 (1996) (internal quotation marks omitted); see
Retail Clerks v. Schermerhorn, 375 U. S. 96, 103 (1963). [
Medtronic: "[O]ur analysis of the scope of the statute's pre-emption is guided by our oft-repeated comment, initially made in
Retail Clerks v. Schermerhorn, 375 U.S. 96, 103, ... (1963), that 'the purpose of Congress is the ultimate touch-stone' in every pre-emption case."] Second, "[i]n all pre-emption cases, and particularly in those in which Congress has 'legislated ... in a field which the States have traditionally occupied', ... we 'start with the assumption that the historic police powers of the States were not to be superseded by the Federal Act unless that was the clear and manifest purpose of Congress'."

Lorillard Tobacco Co. v. Reilly, 533 U.S. 525 (2001), at 541–542 (citation omitted): Because "federal law is said to bar state action in [a] fiel[d] of traditional state regulation", namely, advertising, we "wor[k] on the assumption that the historic police powers of the States [a]re not to be superseded by the Federal Act unless that [is] the clear and manifest purpose of Congress.
Federal agency administration guiding principles (Mandatory authority for independent agencies created by executive order and Cabinet departments; not binding on judicially-created tribunals; congressionally-created independent regulatory agencies are encouraged to comply) Executive Order 13132 of August 4, 1999 – See 64 Fed. Reg. 43, 255 – August 10, 1999, Sec. 4. Special Requirements for Preemption. Agencies, in taking action that preempts State law, shall act in strict accordance with governing law. (a) Agencies shall construe, in regulations and otherwise, a Federal statute to preempt State law only where the statute contains an express preemption provision or there is some other clear evidence that the Congress intended preemption of State law, or where the exercise of State authority conflicts with the exercise of Federal authority under the Federal statute. (b) Where a Federal statute does not preempt State law (as addressed in subsection (a) of this section), agencies shall construe any authorization in the statute for the issuance of regulations as authorizing preemption of State law by rulemaking only when the exercise of State authority directly conflicts with the exercise of Federal authority under the Federal statute or there is clear evidence to conclude that the Congress intended the agency to have the authority to preempt State law. (c) Any regulatory preemption of State law shall be restricted to the minimum level necessary to achieve the objectives of the statute pursuant to which the regulations are promulgated. (d) When an agency foresees the possibility of a conflict between State law and Federally protected interests within its area of regulatory responsibility, the agency shall consult, to the extent practicable, with appropriate State and local officials in an effort to avoid such a conflict. (e) When an agency proposes to act through adjudication or rulemaking to preempt State law, the agency shall provide all affected State and local officials notice and an opportunity for appropriate participation in the proceedings. ==Evidence of congressional intent to preempt==
