Trump's tariffs were already ever-changing. Now, court fights add to the uncertainty
There has been a reprieve for Donald Trump's tariff agenda, but its future remains in doubt.
On Thursday, local time, the ruling by the International Trade Court seemed a devastating blow to Trump's signature "Liberation Day" tariff and his earlier punitive tariffs on Mexico, Canada and China.
The three judges — two appointed by Republicans, one by a Democrat — said the president had overstepped his powers by implementing the tariffs.
The Trump administration was quickly on the offensive, once again attacking what it calls "activist" judges for stymieing its agenda.
It appealed the ruling, arguing the president possessed the power to implement the tariffs to address a self-declared economic emergency.
Later on Thursday, the US Court of Appeals for the Federal Circuit reinstated the Trump tariffs while the ruling is considered.
It means importers will continue to pay the tariffs — at least in the short term.
Trump's second term tariff policy was already tumultuous with multiple alterations to the rates over the past few months.
These court rulings only further muddy already murky waters.
Since his return to office, Trump has shown a passion for exercising the powers bestowed upon his discretion.
He seemed particularly taken with the power of executive orders.
He's signed about 160 of them in his first four months.
For comparison, that's roughly the same number Joe Biden signed in his full four-year term.
The problem with executive orders is that they're bounded by the laws Congress has enacted and can always be overturned by the next holder of the office.
So, most presidents try to marshal the forces of Congress to make new laws, which are far harder to rescind.
But that takes time — and Trump says there are lots of issues that need addressing now.
He says he can't wait for Congress to act.
He's used executive orders to address a range of "national emergencies".
These include an "energy emergency", which he's used to push for more oil and gas exploration; a "southern border emergency", used to direct further resources to halt illegal migration; and the "economic emergency", which he's sought to address with a range of tariffs.
There have been multiple legal challenges to how he's used these declared emergencies to change rules and policies.
It seems all but certain that the most senior court in the land — the US Supreme Court — will eventually need to settle the matter.
It should be noted, though, that Trump has used multiple different powers to implement his tariff agenda.
Not all rely on declarations of national emergencies.
The 25 per cent tariff being levied on steel, aluminium and automotive imports into the US isn't at risk in this case.
It's possible the Trump administration will now move from sweeping country-specific tariffs to more industry-specific tariffs instead.
The White House says it's looking at all options.
US stocks surged after the ruling by the Trade Court, enthusiastic that it could mean a shortened shelf life for the tariffs.
On the whole, investors like much of Trump's economic agenda — particularly the promises of low taxes and less regulation.
They think these policies will lead to higher economic growth, even if it's at the cost of government services or environmental protection.
Let's call these Trump's pro-growth policies.
What investors don't like is his love of tariffs, which push up prices and hurt trade.
Let's call these Trump's anti-growth policies.
Investors are hoping the pro-growth policies are passed by Congress and signed off by Trump, while the anti-growth policies are ditched at some point.
This court decision gives Trump an easy out.
He could claim he fought hard to implement high tariffs to incentivise businesses to bring jobs back to the US — as promised in his campaign — only to see the plan blocked by judges.
Republicans would be hoping that by the time the midterm elections roll around next November, business profits and economic growth are booming because of the tax cuts and deregulation drive — setting them up to hold onto the House and Senate.
Whereas if massive tariffs are kept in place for a prolonged period, American consumers would be confronted with higher prices for imported goods.
Most economists also think the chance of a recession is increased.
Under this scenario, Republicans could instead find themselves asking voters to keep them in charge at a time of major economic insecurity.
While Trump himself won't be up for re-election, he has a lot at stake personally.
If Democrats are swept back into power, it's highly likely he'll again face impeachment.
If his political fortunes have fallen so far that even some Republicans have turned on him, he could even be thrown out of office.
The problem for those who want Trump to take the obvious off-ramp is that he's long espoused the power of tariffs.
It's seemingly one of his longest and most tightly held political beliefs despite current economic orthodox being that broadly imposed tariffs stifle growth.
He's also sensitive to accusations of cowardice.
This week, a reporter asked him about the recently coined term "TACO" — which stands for Trump Always Chickens Out.
It refers to Trump's habit of first imposing massive tariffs before backing away from them.
Trump reacted furiously.
"I chicken out? I've never heard that," he said.
"Don't ever say what you said," he later added.
"That's a nasty question. To me, that's the nastiest question."
But the evidence is mounting that Trump's most outlandish tariff threats aren't implemented for long.
After ratcheting the tariff on most Chinese goods to 145 per cent, he's now dropped it to 30 per cent.
Besides China, none of the country-specific reciprocal tariffs announced on his so called liberation day were ever implemented.
Last week, he threatened to hit the European Union with a 50 per cent tariff — but that too was delayed a few days later.
Still, the universal 10 per cent tariff remains in place for most countries with the threat of a major increase in reciprocal tariffs rates looming.
The risk can't be ignored completely.
When Trump announced a pause on the country-specific higher reciprocal tariffs, it was supposed to allow time to negotiate and then announce a raft of new deals.
Trade adviser and key architect of Trump's trade policies Peter Navarro spoke about securing "90 deals in 90 days", with Trump serving as the chief negotiator.
But about halfway through the 90 days, the only agreement has been with the UK — and that wasn't much of a deal.
No movement on the level of tariff, just some extra access for certain products.
With the legality of Trump's tariffs a live question, it would be understandable for other countries to wait and see how the court battles play out.
While the White House Press Secretary Karoline Leavitt says "Other countries around the world have faith in the Negotiator-in-Chief, President Donald J. Trump," it will be the US court system that determines just how much power he wields in such negotiations.
Trump claims to have two, in some ways contradictory, motives for waging his tariff battle.
He wants to use them to incentivise businesses to bring production back to the US by making it prohibitively expensive to make things overseas.
He also wants to use the threat of tariffs to force other governments to bend to his will, particularly by opening access to their markets for US goods.
The ongoing uncertainty of his legal authority to wage his trade war makes both goals more difficult to achieve.
Business doesn't want to go through the expensive process of moving production if the tariffs won't last, and why would a foreign government try to strike a deal with a leader who doesn't have control of the tariff stick he threatens to wield?

Offshore wind partners given more time to consider involvement in Hunter project
Novocastrian Wind Pty Ltd has been given more time to weigh up its involvement in the Hunter's offshore wind project due to uncertainty that is rocking the global industry. Project partners, Australian company Oceanex and Norwegian energy giant Equinor, were offered a feasibility licence for their two GW project in late February. The government initially gave the partners 90 days to consider the offer, given that the offer was made just prior to the federal election campaign. The timeframe expired last week. The government has since agreed to allow another 90 days for the partners to develop their commercial arrangements, given the challenges facing the industry. While Oceanex is keen to move ahead, Equinor's recent public statements have raised questions about its commitment to the project. If they are unable to resolve their issues, the government could be forced to call for fresh licence applications for the zone, which it declared in 2023. Oceanex founder and chief executive Andy Evans told the Newcastle Herald that the company remained committed to making the Novocastrian Wind project a reality. "We love the region and the people, and we know it's the perfect place to start a floating offshore wind industry in Australia," he said. In previous statements, Equinor has said that it was assessing the government's offer as part of the prescribed legislative framework. On Tuesday, a spokeswoman said the company continued to believe Newcastle had strong characteristics for an offshore wind industry, including a legacy of heavy industry and innovation, supply chain capabilities, infrastructure and wind resources offshore. "We will continue to assess the feasibility licence, and if accepted, the initial focus will be on community and stakeholder engagement, supply chain development, as well as environmental studies and baseline surveys," the spokeswoman said. "This phase is expected to take up to seven years, and consultation with stakeholders is a key component of environmental approvals under legislative and regulatory requirements." The Herald understands Equinor will also have to make significant milestone payments to its commercial partner if it signs off on the licence. Equinor, formerly known as Statoil, changed its name in 2018 as part of a rebrand away from oil and gas to broader energy generation. Throughout 2024, it announced a retreat from offshore wind, closing its office in Vietnam and cancelling all offshore wind projects in Portugal and Spain. It also reduced the number of employees in its renewable energy division by 20 per cent, roughly a cut of 250 jobs globally. In February 2025, as part of its Q4 and 2024 annual results, Equinor announced it would halve its renewables investment from US$ 10 billion to US$5 billion. It has also lowered its capacity for renewables from 12 - 16 GW to between 10 -12 GW. The company recently recommenced construction of its 810-megawatt Empire Wind 1 project off downstate New York after the Trump administration claimed there were "serious issues with respect to the project approvals". Aside from offshore wind, the company has been lifting its investments in offshore oil, including plans to invest US$6.7 billion each year through to 2035 in Norway's offshore oil sector. Overall, it is increasing oil and gas production, aiming for a 10 per cent growth from 2024 to 2027. In April 2025, institutional investors, including a Danish and Swedish pension fund, as well as Australia's Centre for Corporate Responsibility, expressed their concerns at the incompatibility of the plans with Equinor's stated commitment to net zero. Despite a high-profile campaign against the Hunter Offshore Wind Project in the lead-up to last month's federal election, Labor increased its majority in the seat of Paterson. Minister for Climate Change and Energy Chris Bowen said on Tuesday that the offshore wind had huge economic and employment potential for the Hunter and Australia. "When you're starting a new industry, you'll always have challenges to overcome, but the future remains potentially very strong for offshore wind and all the jobs that it involves," he said. Mr Bowen was in Western Australia's Bunbury offshore wind zone on Tuesday to offer a feasibility licence to Bunbury Offshore Wind Farm Pty Ltd to operate in the northern part of the zone. The project has the potential to deliver 1.5 gigawatts of reliable renewable electricity, enough to power about one million homes, and could employ 900 workers during construction with 450 ongoing jobs. The Minister has shortlisted two projects: one from Westward Wind Pty Ltd and an additional project from Bunbury Offshore Wind Pty Ltd for a preliminary feasibility licence in the southern area of the zone. The two applicants will now seek to resolve the overlap between them.

Missing 15-year-old girl who had disturbing chats with men is found safe in Colorado
A 15-year-old girl who vanished nearly six weeks ago in Utah — prompting the investigation of three men, including at least one who shared disturbing chats while trying to get her to meet him — has been found safe more than 800 kilometres away in Colorado, according to authorities. Alisa Petrov, 15, from South Jordan, walked into the Colorado Springs Police Department on Sunday evening, six weeks after she disappeared, police said, according to KUTV. She was in good health, but police have not yet determined how she got to the police station or if she was held against her will, the outlet reported. Ms Petrov was reported missing on April 21, two days after her final message to a 41-year-old man with whom she had been having a series of conversations, according to an affidavit obtained by KSL TV. 'I'M RUNNING AWAY. Please don't contact me,' Ms Petrov wrote at 12:34am, local time on April 19 in a message to an unnamed man from Herriman, Utah, whom she met on Discord, the report said. The man was later identified as Samuel Teancum Mitchell, after police conducted a reverse search of the phone number he provided to Ms Petrov, KUTV reported. The illicit messages included discussions about condoms and sex games, as well as planning to meet in person, according to the affidavit. Messages were discovered on Ms Petrov's iPad, which she left behind in her bedroom. She had shared her Snapchat username with him, and some messages may have been deleted, according to the warrant. Mitchell, 41, was arrested Wednesday and charged with five counts of sexual exploitation of a minor, a second-degree felony, and enticement of a minor. Two other men were also charged for communicating with Ms Petrov before her disappearance, KSL reported. William Taylor Glines, 37, is in custody in Texas, and a second suspect, Matthew Nicholas Menard, 35, of Florida, turned himself in on Wednesday night, the outlet said. Glines has been charged with aggravated sexual exploitation of a minor, attempted aggravated sexual exploitation of a minor, first-degree felonies, and criminal solicitation, records indicate. Menard was also charged with aggravated sexual exploitation of a minor, enticing a minor, and three counts of criminal solicitation. Petrov was last seen on security video leaving a train platform in Provo, KUTV reported. Her family had previously offered a US$20,000 reward for any information leading to her safe return.

Uncertainty about Trump's tariffs has contributed to weaker outlook for Australia's economy, RBA official says
Australia's economy will experience weaker growth, lower inflation and a slightly weaker labour market as a consequence of US President Donald Trump's tariffs, an RBA official says. Sarah Hunter, an assistant governor at the Reserve Bank, said the uncertainty caused by Mr Trump's tariffs — with their constantly shifting rules and levels — was also making it harder to forecast where the global economy was heading. She said Australia's economy, at this point, probably would not suffer a material direct negative impact from the tariffs. But the uncertainty sparked by the tariffs would hurt Australia, and our economy would be hit in other indirect ways, she said. She said that explained why the RBA revised its official forecasts recently to anticipate weaker growth, lower inflation and a slightly higher unemployment rate over the next 12 months. "Global uncertainty may weigh substantially on domestic activity if uncertainty remains elevated," she warned. She said the RBA Board's decision to cut interest rates last month was also informed by this analysis of the problems that flowed from heightened uncertainty in the global economy. She made her comments in a speech to the Economic Society of Australia Queensland on Tuesday afternoon. Ms Hunter said uncertainty was "a bit of a slippery concept" and there were lots of ways to try to measure it. She said one way — the economic policy uncertainty index (EPU) — was based on the number of news articles that mentioned policy uncertainty. Another way — the volatility index (VIX) — was a measure that captured how uncertain financial markets were about near-term equity prices. But she said both of those indices saw a sharp rise in uncertainty after Donald Trump's tariff announcement in April, although the VIX has declined in recent weeks. See the graph below. And she said there was "ample evidence" that higher uncertainty could lead to declines in investment, output and employment and Australia was not immune from that dynamic. "Typically, higher uncertainty leads firms to delay decisions that are costly to reverse, like investment and hiring," she said. "This makes sense intuitively because there is value in waiting to see how things are playing out before making a decision that is (at least partially) non-reversible. "Some studies find higher uncertainty also has a measurable impact on household consumption, but this is typically more modest. "Research suggests that the negative impacts of higher policy uncertainty — including trade policy — are largest for businesses, as they typically pull back on investment," she said. She said that if we saw businesses and households responding as they had in the past, then the current level of uncertainty "will weigh materially on global activity". "But the unpredictability and unprecedented nature of the current situation makes it hard to be precise on the size of the impact," she warned. She said at this stage, the RBA's "baseline scenario" for its official forecasts assumed that the prevailing level of global uncertainty would have a "relatively modest drag" on Australia's economy. But she said if a global trade war erupted, we could see a "substantial pull-back in activity" in Australia. Overall, Ms Hunter said the RBA would monitor carefully how things unfolded in coming months. She said the RBA's economists would be watching "key transmission channels" through which the United States' proposed trade tariffs would impact Australia's economy, in their different ways. She said those channels included: And she emphasised how difficult it had become to produce forecasts of economic activity in such a febrile environment. "How will the current unpredictable and uncertain global environment transmit through to the Australian economy?" she asked. "The short answer is, we can't be completely sure. "The broad-based nature of the proposed US tariffs, retaliation from major partners and other policy shifts all have the potential to structurally alter the world economy. "[Our] baseline forecast is for recent global developments to contribute to slower economic growth in Australia and a slightly weaker labour market. "We also anticipate that, overall, the price of tradable goods will be slightly dampened. "Together, these two outcomes mean that inflation is forecast to be a little lower than at the February Statement on Monetary Policy, settling around the midpoint of the 2-3 per cent target range. "This forecast is based on several judgments and assumptions about the potency of the transmission channels I have discussed today," she said.
