Opposition leader Raila Odinga speaks during a news conference at the offices of the National Super Alliance (NASA) coalition in Nairobi, Kenya August 16, 2017. It was not clear if the government planned to appeal the order; government spokesman Eric Kiraithe said he had no immediate comment.
According to NTV, a 14-day suspension of the government's shutdown has been ordered by the High Court, while a legal challenge can be heard.
The government has responded by declaring the opposition movement a criminal organization and investigating "conspirators" in Tuesday's ceremony.
He pasted the order on the gate of the authority, but the men tore it down, he said.
Also on Friday, firebrand opposition politician Miguna Miguna was detained in a dawn raid on his Nairobi home and later released on bail of 50 000 Kenyan shillings ($500), his lawyer Nelson Havi told Reuters.
While Miguna lost in his bid to become governor of Nairobi past year and holds no official position within NASA, he is the self-styled "general" of the party's "National Resistance Movement" wing which is tasked with implementing a threatened programme of civil disobedience and boycotts.
Activist Okiya Omtata says police are preventing him from serving the order to Kenya's communications authority.
The opposition has vowed they will not recognise the election of President Kenyatta in the repeat elections in October, which Mr Odinga boycotted.
However, there was no response from the government or any explanation as to why the channels were still off air eight hours following the judgment. The laws are clear.
"As soon as we serve the order this morning I expect the stations to be back on", he said. "That's why the court ruled as they did".
The U.S. Department of State, in a statement issued by Ms Heather Nauert, Department Spokesperson, said: "We reject actions that undermine Kenya's Constitution and the rule of law", she wrote.
Initially, there were fears of chaos due to confrontation between the police and opposition supporters after the government banned the event. "The government has got its own reasons for shutting down these media houses for their own security".
Member of Parliament representing Ruaraka Constituency, Tom Joseph Kajwang, has been arrested and is expected to be charged in court for participation in illegal assembly and administering an illegal oath on Raila Odinga as People's President.
