A U.K. regulatory agency ordered research firm Cambridge Analytica to hand over its data on an American voter last week.
The U.K. Information Commissioner’s Office (ICO) on Friday ordered the firm to hand over all of its information on American professor David Carroll, according to The Guardian.
Carroll was able to request the information under British data protection laws because his voter data had been processed in the U.K.
“This should solve a lot of mysteries about what the company did with data and where it got it from,” Carroll said in a statement, according to The Guardian. “I hope that it will help the ongoing investigations in my country and yours, and other places like Canada. There’s a lot of questions that no one has been able to answer until now so hopefully, this will be a major breakthrough in our understanding of what it did.”
The firm, which announced it was shutting down last week, has 30 weeks to comply with or appeal the order.
The case could set a precedent for the 240 million other U.S. voters looking to get their data back under British data laws.
The company has been in hot water since March when it was revealed that it had improperly obtained data on 87 million Facebook users.
Cambridge Analytica reportedly used the Facebook data it obtained from a researcher’s third-party app to help build data models to be used for the Trump campaign and super PACs including Bolton’s.
