Yahoo said Thursday the government threatened to fine the company $250,000 a day if it did not comply with demands to go along with an expansion of U.S. surveillance by surrendering online information, a step the company regarded as unconstitutional.
The outlines of Yahoo's secret and ultimately unsuccessful court fight against government surveillance emerged when a federal judge ordered the unsealing of some material about Yahoo's court challenge.
In a statement, Yahoo said the government amended a law to demand user information from online services, prompting a challenge in 2007 during the George W. Bush administration.

''Our challenge, and a later appeal in the case, did not succeed,'' Yahoo general counsel Ron Bell said in a statement.
The new material about the case underscores ''how we had to fight every step of the way to challenge the U.S. government's surveillance efforts,'' Bell added. ''At one point, the U.S. government threatened the imposition of $250,000 in fines per day if we refused to comply.''
Bell said the Foreign Intelligence Surveillance Court upheld the predecessor to Section 702 of the FISA Amendments Act. Section 702 refers to the program called PRISM, which gave the government access to online communications by users of Yahoo.
Former National Security Agency contractor Edward Snowden disclosed the program last year.
Yahoo said it is committed to protecting users' data and that it will continue to contest requests and laws that it considers unlawful, unclear or overly broad.
''We consider this an important win for transparency, and hope that these records help promote informed discussion about the relationship between privacy, due process and intelligence gathering,'' said Bell.
The newly released documents show that the Bush administration was taking a hard line and was miffed that Yahoo had even been allowed to get into court with its complaint.
In sum, the Foreign Intelligence Surveillance Court erred in permitting Yahoo to challenge the directives, said a court brief signed by then-U.S. Attorney General Michael Mukasey.
Yahoo was arguing that what the Bush administration was doing violated the Fourth Amendment rights of customers of Yahoo.
