WhatsApp said they did not have access to the details requested."The suspension of service apparently violates the fundamental precept of freedom of expression and communication," the Supreme Court said in its ruling. Mr Lewandowski pointed out that the lower court judge's decision seemed "not very reasonable and not very proportional".WhatsApp - owned by social media giant Facebook since February 2015 - gradually resumed normal service after the court's ruling, correspondents say.Image source, AFPImage caption, A huge proportion of Brazil's online population use the free WhatsApp service - partly because making mobile calls is expensiveEarlier in the day, lower court Judge Daniela Barbosa ordered the suspension of WhatsApp, accusing its parent company Facebook of failing "to provide information that will be critical to the success of an investigation and later to bolster the criminal case".It is not clear which investigation she is referring to, but she said the firm had been repeatedly asked to provide messages to police investigators in the city of Caxias, north of Rio.Taking to Facebook, WhatsApp CEO Jan Koum said it was "shocking that less than two months after Brazilian people and lawmakers loudly rejected blocks of services like WhatsApp, history is repeating itself".He was referring to its suspension for 72 hours in May, which forced users to turn to alternative services - a huge proportion of the internet-using population in a country with some of the world's highest mobile phone charges.Twitter users responded with frustration - and, in many cases, with humour: Image source, TwitterImage caption, "Exclusive images of the office of [rival messaging service] Telegram after the judge's decision to block WhatsApp in Brazil"WhatsApp also argues that it cannot share information, because its encrypted communications mean, external "only you and the person you're communicating with can read what is sent".Technology commentators suggest regular interruptions to service could dent WhatsApp's popularity.More on this story
