A U.S. District Court Judge has invalidated a Trump administration executive order that suspended offshore wind power development and certain land-based projects. The order, which called for a pause on all permitting for wind power on federal land and waters until a review was conducted, faced legal challenges from states and wind power organizations citing its arbitrary nature.

After more than 10 months of delay in re-evaluating the permitting process, it was revealed that little progress had been made in formulating a review. Judge Patti Saris criticized the lack of substantive explanation for the suspension, emphasizing that the government failed to provide sufficient justification beyond the executive order and a Department of the Interior memo.

While the court’s decision to lift the suspension does not automatically greenlight any pending wind projects, it sets the stage for potential future legal battles between states, project owners, and federal agencies. The previous administration had prioritized offshore wind development, a crucial component of climate strategies in several northeastern states facing challenges in onshore renewable energy deployment.

Meta, formerly known as Facebook, has agreed to modify its business model in the European Union, moving away from the controversial ‘pay or consent’ approach to data tracking. This shift comes as the company aims to resolve ongoing regulatory challenges within the EU and avoid additional fines, particularly in light of increasing tensions with US authorities over digital regulations.

Following discussions with the European Commission, Meta has introduced an alternative for users in the EU, offering a reduced-advertisement experience on Facebook and Instagram for those who opt out of personalized ads.

The adjustment is in response to an EU investigation into Meta’s previous practice of requiring users to either agree to data tracking or pay for an ad-free service. The Financial Times reported positive sentiments in October regarding the potential for a mutually satisfactory resolution.

Earlier in April, Meta faced a 200 million euro fine from the commission and was instructed to revise its business model. Failure to comply could have resulted in escalating daily penalties, potentially amounting to 5% of Meta’s global revenue.

Regulators will now evaluate Meta’s changes before determining the next steps in the investigation. While the case remains open, the European Commission views Meta’s adjustments as a positive development, signaling progress in addressing the concerns raised.

The Supreme Court recently heard arguments in a case that could have significant implications for internet service providers (ISPs) regarding their responsibility in addressing online piracy. The case centers on whether ISPs should be required to terminate the accounts of users accused of copyright infringement, particularly in instances of downloading pirated content.

During the oral arguments, justices expressed varying concerns and perspectives on the matter. While some questioned the legal obligations of ISPs under the Digital Millennium Copyright Act (DMCA) when dealing with piracy issues, others hesitated to fully support the demands of copyright holders, such as record labels led by Sony.

One of the key points of contention was how ISPs should address widespread infringement, especially in scenarios like universities with a large number of users. Justice Sonia Sotomayor criticized Cox Communications for what she perceived as a lack of proactive measures in combating infringement, suggesting that ISPs could have taken more decisive actions to address the issue.

The case stems from a previous ruling where Cox was initially ordered to pay over $1 billion for contributory infringement, but had that verdict overturned by the US Court of Appeals for the 4th Circuit. Cox is now seeking clearance from the Supreme Court on the willful contributory infringement charge, while record labels are advocating for a ruling that would compel ISPs to take stricter actions against piracy.
