Trump Imposes 15% Global Tariff Hours After Supreme Court Blocks Previous Tariffs
Trump Imposes 15% Global Tariff Hours After Supreme Court Blocks Previous Tariffs
President Donald Trump has announced a 15 % global tariff on imported goods just hours after the U.S. Supreme Court struck down his earlier tariff programme as unconstitutional. The decision marks a major escalation in U.S. trade policy and signals potential disruptions for global markets.
The Supreme Court, in a 6‑3 ruling, found that Trump overstepped his authority by using emergency powers under the International Emergency Economic Powers Act (IEEPA) to impose sweeping tariffs. The Court ruled that only Congress has the power to levy broad import taxes, effectively invalidating the president’s previous tariffs on most trading partners.
In response, Trump moved swiftly to raise tariffs under Section 122 of the Trade Act of 1974, which allows temporary import duties of up to 15 % for 150 days without congressional approval. Trump described the increase as “fully allowed and legally tested” and indicated his administration will explore additional legally permissible tariffs in the coming months.

Official statements confirmed that the new tariff takes immediate effect, covering imports from all countries. The White House framed the move as a measure to protect U.S. workers and industries from unfair foreign competition, even as analysts warn it could increase costs for consumers and invite retaliatory trade measures from other nations.
Economic and Political Reactions
The Supreme Court decision and Trump’s rapid tariff escalation drew mixed reactions. Business groups and economists cautioned that higher tariffs could disrupt supply chains, increase inflation, and slow economic growth. Some companies have already filed legal claims seeking refunds for previously collected tariffs.
Meanwhile, global trading partners are monitoring the situation closely, warning that the 15 % tariff could strain diplomatic and trade relations. Supporters of Trump’s trade stance argue that tougher tariffs are necessary to address U.S. trade deficits and protect domestic manufacturing.
Section 122 authority expires after 150 days unless Congress extends it, meaning the long-term enforcement of the 15 % tariff may require legislative backing. Analysts say the move highlights the tension between executive authority, judicial oversight, and congressional power in U.S. economic policymaking.
Global Implications
Markets around the world have reacted cautiously to the announcement. Some trading partners may implement retaliatory tariffs, while global supply chains could face disruptions, particularly in consumer electronics, automotive, and industrial sectors. Analysts predict that ongoing uncertainty will affect trade flows and investment decisions in the short term.
Trump’s announcement comes at a politically charged moment, with midterm elections and international trade negotiations influencing domestic and global economic strategies. The move underscores the complex interplay of law, politics, and economics in U.S. trade policy.

Pope Leo XIV Warns Against Letting AI Make Human Decisions
Pope Leo XIV Warns Against Letting AI Make Human Decisions
The rapid advancement of artificial intelligence has prompted a fresh warning from Pope Leo XIV, who says some decisions should never be handed over to algorithms.
The Pope made the remarks at his weekly audience in St Peter’s Square, where he addressed thousands of faithful and reflected on the impact of technology on modern human interaction.
While acknowledging that AI, social media and other forms of technological development can reduce barriers and connect people across great distances, he said they also carry a risk of making human relationships increasingly virtual.
His particular concern was the possibility that society could become accustomed to allowing algorithms to determine matters that should instead be guided by human conscience.
“Ensuring that social relationships have real substance and personal depth” is one way the Christian community seeks to respond to this challenge, he said.
The comments come amid broader concerns about the direction of AI development. Recent security incidents, along with the growing ability of some AI systems to improve their own performance without human intervention, have intensified debate about the technology.
Another major question is whether companies and organisations within the AI sector are capable of regulating themselves effectively as the technology becomes more powerful.
The Pope has previously made AI a major focus of his public interventions. His first major document, the May encyclical “Magnifica Humanitas”, urged efforts to prevent AI from becoming a force that dominates humanity.
The Holy See has also become more active in calls for international rules governing AI, grounding its position in the protection of human dignity. Its initiatives have extended to discussions involving nuclear technology, culture and artistic creation.
The latest warning places the Vatican’s concerns within a wider debate over how humanity should balance the benefits of increasingly powerful AI with the need to keep important decisions under human control.

Islamic Council Condemns Attempted Attack on Holy City of Mecca
Islamic Council Condemns Attempted Attack on Holy City of Mecca
International leaders call for accountability after Saudi defense systems neutralize an incoming drone before it entered protected airspace.
The Organisation of Islamic Cooperation has strongly criticized a failed drone attack directed toward the holy city of Mecca and the surrounding Medina region.
The international group, which represents 57 member nations, stated that any attempt to strike sacred places of worship or harm everyday people goes against basic human decency and international law.
The statement came after Saudi defense forces reported stopping an unmanned aircraft on Tuesday evening. Coalition officials confirmed that defense teams tracked the incoming drone and destroyed it south of Mecca before it could enter protected airspace.
Military representatives explained that keeping visiting worshippers and local communities safe remains an absolute priority, warning that threats against sacred sites will not be tolerated.
The OIC expressed full support for the safety steps Saudi Arabia uses to protect its borders, communities, and historical religious centers.

Although Houthi representatives in Yemen have previously stated that they do not intend to strike holy landmarks, global leaders emphasized that all groups must respect civilian safety and ensure that sacred religious spaces remain free from military conflict.

US Court Blocks Trump Visa Rule Limiting Stay of Foreign Students, Journalists
US Court Blocks Trump Visa Rule Limiting Stay of Foreign Students, Journalists
A federal court in the United States has temporarily blocked the Donald Trump administration from implementing a new immigration rule that would have imposed fixed time limits on how long foreign students, exchange visitors and journalists could remain in the country without applying for extensions.
The ruling, delivered by U.S. District Judge F. Dennis Saylor IV in Boston on Monday, September 14, came just one day before the controversial rule was scheduled to take effect.
The decision provides immediate relief for thousands of Nigerians in the United States, particularly international students, researchers, exchange visitors and journalists whose immigration status could have been affected by the new restrictions.
However, the ruling does not specifically exempt Nigerians. The rule applies broadly to foreign nationals covered by the affected visa categories, meaning Nigerians are among the people who would have been subject to the proposed restrictions.
The Trump administration’s rule, published by the U.S. Department of Homeland Security (DHS) in July, sought to replace the long-standing “duration of status” (D/S) system with fixed admission periods for holders of F, J and I visas.
Under the proposed system, F-1 international students would generally have been admitted for a maximum of four years, while J-1 exchange visitors would also have faced a four-year limit.
Foreign journalists holding I visas would have been permitted to remain for up to 240 days before being required to seek an extension. The Federal Register rule also contained a separate 90-day limit for certain Chinese journalists.
The changes would have represented a major departure from the system that has governed foreign students and researchers in the U.S. for decades.
Under the existing duration-of-status arrangement, eligible students can generally remain in the country for the period necessary to complete their approved programme, provided they maintain their immigration status and comply with the relevant requirements.
The proposed fixed-term system would instead have required many students whose programmes extend beyond four years to seek an extension from U.S. immigration authorities.
Judge Saylor ruled that the Department of Homeland Security had failed to provide an adequate justification for such a significant change.
The judge described the agency’s reasoning as “exceptionally weak”, finding that DHS had not sufficiently addressed the consequences of abandoning the existing system or considered less restrictive alternatives.

The court’s decision also highlighted the potential impact on American universities, research institutions and the wider U.S. economy.
According to the ruling, approximately 1.6 million people hold F visas, while another 500,000 hold J visas. Major American research universities have significant numbers of international students, particularly at postgraduate level.
Saylor warned that implementing the rule could result in substantial financial and educational disruption, including declining international enrolment and increased administrative costs for universities.
He noted that the existing system had facilitated the arrival of millions of foreign students and researchers whose contributions had supported advances in science, medicine and technology as well as economic growth in the United States.
The legal challenge was brought by a coalition representing higher education, immigration and journalistic interests, which argued that the new restrictions would create uncertainty for international students, universities, researchers and journalists.
The groups maintained that forcing students and exchange visitors to repeatedly apply for extensions could disrupt academic programmes, research projects and professional activities.
They also argued that the rule could make American universities less attractive to international students at a time when institutions depend heavily on global talent.
The Trump administration, however, defended the policy as necessary to strengthen immigration enforcement and prevent abuse of the student and exchange-visitor visa system.
DHS General Counsel James Percival criticised the court’s decision, arguing that the existing system could allow people to remain in the United States for excessively long periods while technically maintaining student status.
The administration has particularly raised concerns about individuals who enrol in minimal academic programmes and remain in the country for years.
The court’s decision therefore represents a temporary legal setback for the administration’s effort to impose tighter controls on foreign student visas and other temporary immigration categories.
For Nigerian students in the U.S., the immediate consequence is that the proposed four-year F-1 limit does not take effect while the preliminary injunction remains in force.
Students who need more than four years to complete their programmes are therefore not currently required to leave the United States or obtain an extension solely because of the blocked rule.

The same applies to eligible exchange visitors and foreign journalists who would have been affected by the proposed fixed admission periods.
The ruling also means that the existing immigration framework remains in place while the legal battle continues.
However, Judge Saylor’s decision is a preliminary injunction, not a final judgment on whether the Trump administration has the legal authority to change the visa system.
The administration can continue defending the rule in court, and the final outcome could still change depending on subsequent proceedings or appeals.
A further hearing in the case is expected on October 2, 2026, as the parties continue their legal arguments over the new immigration policy.
The dispute comes amid a broader tightening of U.S. immigration policies under Trump, with the administration seeking greater scrutiny of foreign nationals entering or remaining in the country.
The blocked rule was formally published in the Federal Register on July 17 and was scheduled to become effective on September 15, 2026.
For now, however, foreign students, exchange visitors and journalists covered by the affected visa categories can continue operating under the existing rules while the court proceedings continue.
The ruling could therefore provide temporary certainty for Nigerian students in America, Nigerian researchers, exchange visitors and journalists who had faced the prospect of additional immigration applications and tighter deadlines under the now-blocked policy.
It also leaves open a wider debate over how the United States should balance immigration enforcement and national security with the interests of universities, international education, scientific research, cultural exchange and journalism.
The Federal Register had said the new system was intended to establish fixed periods of admission and clearer procedures for extensions. The court’s intervention means those provisions cannot currently be implemented as scheduled.
The case is consequently being closely watched by American universities and international students, including Nigerians, because any eventual decision could determine whether the U.S. returns permanently to fixed periods of admission or retains the long-standing duration-of-status framework.
For the moment, the key development is that Trump’s proposed visa time limits have been blocked, and the existing rules remain in effect pending further litigation.
