SAO PAULO (AP) — A Brazilian judge struck down an earlier court ruling to suspend messaging service WhatsApp in Latin America's biggest country for 72 hours, reactivating it on Tuesday, the day after it was shut down.
The ruling by Judge Ricardo Mucio Santana de Abreu Lima came just hours after another judge upheld an earlier judicial order suspending WhatsApp's services. The application was working again by Tuesday afternoon.
The suspension had gone into effect Monday shortly after it was ordered by Judge Marcel Maia Montalvao, in the northeastern state of Sergipe.

"Yet again millions of innocent Brazilians are being punished because a court wants WhatsApp to turn over information we repeatedly said we don't have," the messaging service's CEO and co-founder Jan Koum said on his Facebook page after Montalvao's ruling. "We encrypt messages end-to-end on WhatsApp to keep people's information safe and secure, we also don't keep your chat history on our servers."
"We have no intention of compromising the security of our billion users around the world," he added.
Montalvao's suspension was the latest chapter in a dispute between Brazilian law enforcement and Facebook, which bought WhatsApp in 2014.
Calls to Facebook's offices in Sao Paulo went unanswered on Tuesday.
In March, Facebook's most senior representative in Latin America was detained in Sao Paulo and held overnight.
At the time, a spokeswoman for federal police in Sergipe, Monica Horta, said investigators had requested content from a WhatsApp messaging group as well as other data, including geolocation. Investigators first contacted WhatsApp several months earlier but hadn't received a response, Horta said.
Brazilian authorities also clashed with Facebook in December, when a judicial order forced telecoms to block WhatsApp for about 12 hours over its alleged refusal to cooperate with a police inquiry.
Facebook CEO Mark Zuckerberg at the time said he was "stunned" by the "extreme decision
