Uber loses UK supreme court appeal over tax on private-hire rivals | Uber

Uber’s rival taxi operators will not have to pay 20% VAT on their profits outside London after a UK supreme court verdict in a long-running case.
The court ruled that private-hire operators do not enter into a contract with passengers, dismissing an Uber appeal. Private-hire firms declared the verdict to be a “triumph for the sector” after a three-year legal battle, which they had said could end with fares rising sharply for passengers.
Uber had brought the case after a 2021 supreme court decision that its drivers were workers, which had an impact on its tax and other obligations.
The company sought a declaration that private-hire taxi operators enter into a contract with passengers and the high court in London ruled in its favour in 2023.
That decision meant that operators would have to pay VAT at 20%, but the ruling was reversed by the court of appeal in July last year after a challenge by the private hire operators Delta Taxis and the platform Veezu.
Uber appealed to the supreme court, which on Tuesday unanimously dismissed the US company’s case.
The Veezu chief legal officer, Nia Cooper, said: “This decision is a triumph for the UK private-hire sector. The unanimous verdict ends a three-year legal battle and confirms that operators can continue to choose which business model they adopt to run their business.”
She said the outcome would protect passengers from threatened fare increases and lessen the burdens on licensing authorities. “Uber was seeking a declaration that would have resulted in 20% VAT being charged on all PHV fares,” she said.
“This ruling also shows that British-owned businesses can stand up against global giants that attempt to use litigation as a tactic to shape the sector to suit their business model.”
An Uber spokesperson said: “The supreme court ruling confirms that different contractual protections apply for people booking trips in London compared to the rest of England and Wales. The ruling has no impact on Uber’s application of VAT, which has been upheld twice by other courts.”
In a separate case, the Estonian ride-hailing and food-delivery startup Bolt this year defeated an appeal by the UK tax authority HMRC on what exactly it has to pay VAT on at 20%.
HMRC has since been granted permission to challenge the ruling that Bolt is only liable for VAT on its margin, rather than the full cost of the trip, at the court of appeal.

Pentagon research official wants to have AI on every desktop in 6 to 9 months

The Pentagon is angling to introduce artificial intelligence across its workforce within nine months following the reorganization of its key AI office.
Emil Michael, under secretary of defense for research and engineering at the Department of Defense, talked about the agency’s plans for introducing AI to its operations as it continues its modernization journey.
“We want to have an AI capability on every desktop — 3 million desktops — in six or nine months,” Michael said during a Politico event on Tuesday. “We want to have it focus on applications for corporate use cases like efficiency, like you would use in your own company … for intelligence and for warfighting.”
This announcement follows the recent shakeups and restructuring of the Pentagon’s main artificial intelligence office. A senior defense official said the Chief Digital and Artificial Intelligence Office will serve as a new addition to the department’s research portfolio.
Michael also said he is “excited” about the restructured CDAO, adding that its new role will pivot to a focus on research that is similar to the Defense Advanced Research Projects Agency and Missile Defense Agency. This change is intended to enhance research and engineering priorities that will help advance AI for use by the armed forces and not take agency focus away from AI deployment and innovation.
“To add AI to that portfolio means it gets a lot of muscle to it,” he said. “So I’m spending at least a third of my time –– maybe half –– rethinking how the AI deployment strategy is going to be at DOD.”
Applications coming out of the CDAO and related agencies will then be tailored to corporate workloads, such as efficiency-related work, according to Michael, along with intelligence and warfighting needs.
The Pentagon first stood up the CDAO and brought on its first chief digital and artificial intelligence officer in 2022 to advance the agency’s AI efforts.
The restructuring of the CDAO this year garnered attention due to its pivotal role in investigating the defense applications of emerging technologies and defense acquisition activities. Job cuts within the office added another layer of concern, with reports estimating a 60% reduction in the CDAO workforce.

Pentagon CTO wants AI on every desktop in 6 to 9 months

The Pentagon aims to get AI tools to its entire workforce next year, the department’s chief technical officer said one month after being given control of its main AI office.
“We want to have an AI capability on every desktop — 3 million desktops — in six or nine months,” Emil Michael, defense undersecretary for research and engineering, said at a Politico event on Tuesday. “We want to have it focus on applications for corporate use cases like efficiency, like you would use in your own company…for intelligence and for warfighting.”
Four weeks ago, the Chief Digital and Artificial Intelligence Office was demoted from reporting to Deputy Defense Secretary Stephen Feinberg to Michael, a subordinate.
Michael said CDAO will become a research body like the Defense Advanced Research Projects Agency and Missile Defense Agency. He said the change is meant to boost research and engineering into AI for the military, but not reduce its efforts to deploy AI and make innovations.
“To add AI to that portfolio means it gets a lot of muscle to it,” he said. “So I’m spending at least a third of my time—maybe half—rethinking how the AI-deployment strategy is going to be at DOD.”
He said applications would emerge from the CDAO and related agencies that will be tailored to corporate workloads.
The Pentagon created the CDAO in 2022 to advance the agency’s AI efforts and look into defense applications for emerging technologies. The office’s restructuring earlier this year garnered attention. Job cuts within the office added another layer of concern, with reports estimating a 60% reduction in the CDAO workforce.

Panelists Will Question Who Controls AI | ACS CC News
Artificial intelligence (AI) has become one of the fastest-growing technologies in the world today. In many industries, individuals and organizations are racing to better understand AI and incorporate it into their work. Surgery is no exception, and that is why Clinical Congress 2025 has made AI one of the six themes of its Opening Day Thematic Sessions.
The first full day of the conference, Sunday, October 5, will include two back-to-back Panel Sessions on AI. The first session, “Using ChatGPT and AI for Beginners” (PS104), offers a foundation for surgeons not yet well versed in AI. The second, “AI: Who Is In Control?” (PS 110), will offer insights into the potential upsides and drawbacks of AI use, as well as its limitations and possible future applications, so that surgeons can involve this technology in their clinical care safely and effectively.
“AI: Who Is In Control?” will be moderated by Anna N. Miller, MD, FACS, an orthopaedic surgeon at Dartmouth Hitchcock Medical Center in Lebanon, New Hampshire, and Gabriel Brat, MD, MPH, MSc, FACS, a trauma and acute care surgeon at Beth Israel Deaconess Medical Center and an assistant professor at Harvard Medical School, both in Boston, Massachusetts.
In an interview, Dr. Brat shared his view that the use of AI is not likely to replace surgeons or decrease the need for surgical skills or decision-making. “It’s not an algorithm that’s going to be throwing the stitch. It’s still the surgeon.”
Nonetheless, he said that the starting presumption of the session is that AI is likely to be highly transformative to the profession over time.
“Once it has significant uptake, it’ll really change elements of how we think about surgery,” he said, including creating meaningful opportunities for improvements.
The key question of the session, therefore, is not whether to engage with AI, but to do so in ways that ensure the best outcomes: “We as surgeons need to have a role in defining how to do so safely and effectively. Otherwise, people will start to use these tools, and we will be swept along with a movement as opposed to controlling it.”
To that end, Dr. Brat explained that the session will offer “a really strong translational focus by people who have been in the trenches working with these technologies.” He and Dr. Miller have specifically chosen an “all-star panel” designed to represent academia, healthcare associations, and industry.
The panelists include Rachael A. Callcut, MD, MSPH, FACS, who is the division chief of trauma, acute care surgery and surgical critical care as well as associate dean of data science and innovation at the University of California-Davis Health in Sacramento, California. She will share the perspective on AI from academic surgery.
Genevieve Melton-Meaux, MD, PhD, FACS, FACMI, the inaugural ACS Chief Health Informatics Officer, will present on AI usage in healthcare associations. She also is a colorectal surgeon and the senior associate dean for health informatics and data science at the University of Minnesota and chief health informatics and AI officer for Fairview Health Services, both in Minneapolis.
Finally, Khan Siddiqui, MD, a radiologist and serial entrepreneur who is the cofounder, chairman, and CEO of a company called HOPPR AI, will present the view from industry. HOPPR AI is a for-profit company focused on building AI apps for medical imaging. As a radiologist, Dr. Siddiqui represents a medical specialty that is thought to likely undergo sweeping change as AI is incorporated into image-reading and diagnosis. His comments will focus on professional insights relevant to surgeons.
Their presentations will provide insights on general usage of AI at present, as well as predictions on what the landscape for AI in healthcare will look like in approximately 5 years. The session will include advice on what approaches to AI may be most effective for surgeons interested in ensuring positive outcomes and avoiding negative ones.
Additional information on AI usage pervades Clinical Congress 2025. In addition to various sessions that will comment on AI throughout the 4 days of the conference, various researchers will present studies that involve AI in their methods, starting presumptions, and/or potential applications to practice.
