DOJ seen ramping up ‘false claims’ cases over alleged tariff evasion

The Trump administration is ramping up legal action against alleged tariff evaders through direct enforcement of trade laws as well as more novel use of the False Claims Act, further raising uncertainty for importers dealing with shifting tariff rates and exemptions, former Commerce and Justice department lawyers said during a webinar on Tuesday. “There's just a lot of uncertainty, and uncertainty can breed investigations and compliance risk,” Burden Walker, a former deputy assistant attorney general who’s now a partner at...

State, federal Democrats urge Supreme Court to reject Trump’s IEEPA tariffs

Democrats in Congress and the Washington state government are pushing the Supreme Court to strike down President Trump’s International Emergency Economic Powers Act tariffs on separation-of-powers grounds, claiming that allowing the duties to stand would allow the president to seize “core” legislative powers in defiance of the constitution. “Only Congress, not the President, has the power to ‘lay and collect Taxes, Duties, Imposts and Excises,’ and Congress cannot delegate those powers to the President. The President’s exercise of power here...

Supreme Court sets lengthened hearing in IEEPA tariff suit

The Supreme Court will expand its Nov. 5 hearing on the challenges to President Trump’s International Emergency Economic Powers Act tariffs to allow for separate presentations from lawyers for state and private plaintiffs, but the justices will not let competing coalitions of private importers make their own arguments even though they disagree with each other on key legal issues. A pair of scheduling orders issued midday on Oct. 23 as entries in the electronic docket for the tariff suit say...

Democratic AGs say Trump’s IEEPA tariffs go against ‘common sense’

A group of Democratic state attorneys general told the Supreme Court on Monday that “common sense” shows President Trump’s International Emergency Economic Powers Act tariffs are illegal, arguing in a final written brief ahead of a November hearing that context, history and constitutional principles all show that the duties exceed IEEPA’s authority to “regulate” imports. “Every significant piece of context points in the same direction here. IEEPA does not use the terms that Congress typically uses to authorize tariffs, and...

CIT renews stay on de minimis suit, awaiting Supreme Court’s tariff decision

The Court of International Trade is refusing to lift its stay on litigation over President Trump’s executive orders that wound down the de minimis tariff exemption for packages worth $800 or less, electing instead to keep the suit on hold until the Supreme Court decides related challenges over the administration’s “emergency” duties on most U.S. trading partners. Late on Oct. 20, a three-judge CIT panel entered an order in the de minimis suit rejecting a request by the plaintiff, a...

Importers warn Supreme Court against upholding ‘unlimited’ tariff powers

A Supreme Court decision in favor of President Trump’s International Emergency Economic Powers Act tariffs would give the executive “unlimited” power to set, revoke and change tariff rates with no meaningful oversight from the courts or Congress, plaintiffs argued Monday in their final round of written briefs for the litigation. “If the IEEPA tariffs are upheld, this and future Presidents would ‘enjoy virtually unlimited power to rewrite’ U.S. tariff laws -- by adding, increasing, or decreasing taxes on imports --...

Supreme Court rejects tribal members’ bid to intervene in tariff suit

The Supreme Court will not fold claims that President Trump’s International Emergency Economic Powers Act tariffs infringe on tribal commerce rights into broader litigation over the duties’ legality, it announced in a Monday morning order. As part of their Oct. 14 order list compiling decisions on dozens of pending motions and petitions from the previous week, the justices denied without comment tribal plaintiffs’ bid to consolidate their claims about IEEPA tariffs into the suits already pending at the Supreme Court...

Consumer group touts June Supreme Court decision to boost tariff challenge

A consumer-rights group is arguing that a Supreme Court decision handed down in June undercuts President Trump’s claim that the International Emergency Economic Powers Act gives him sweeping tariff authority, escalating a long-simmering fight that has previously focused on how lower courts should interpret that ruling into a push for the justices to explicitly say what it means for tariffs. Consumer Watchdog, a nonprofit consumer-protection organization, filed an amicus brief in the Supreme Court litigation over Trump’s IEEPA tariffs on...

Analysts see ‘coin toss’ odds for Supreme Court tariff suit

The Supreme Court challenge of President Trump’s International Emergency Economic Powers Act tariffs is close to a “coin toss,” legal analysts say, giving a slight advantage to the challengers in part because the administration could quickly replace the current duties using other statutes and thus limit the policy impacts of a loss. However, they said during a Sept. 30 webinar hosted by the Budget Lab, Yale University’s non-partisan economic policy research center, such a decision could still set off a...

Citing divergent claims, IEEPA plaintiffs ask Supreme Court to expand tariff hearing

States, private companies and individuals challenging President Trump’s “emergency” tariffs are asking the Supreme Court to give each set of plaintiffs a chance to present their own arguments at a hotly anticipated Nov. 5 hearing, setting up what would be a complex, five-way proceeding if the justices grant every pending request. Splitting argument among the separate groups of plaintiffs “will ensure that the various interests are adequately represented before the Court. It will also ensure that the fundamentally important statutory...
