Microsoft launched a lawsuit against the Justice Department, saying the government should not be able to prevent companies from notifying customers that law enforcement officials have requested their e-mails and data.
The lawsuit argues it’s unconstitutional to prevent companies from informing their customers of the requests, ABC News reports. 
“Microsoft brings this case because its customers have a right to know when the government obtains a warrant to read their emails, and because Microsoft has a right to tell them,” the tech giant says in its lawsuit.
Microsoft said the government often issues orders requiring secrecy.
The Justice Department declined to comment on the lawsuit, saying, “We are reviewing the filing.”
