Earlier in July, Labour Party's donor Michael Foster contested the party's decision to automatically put Corbyn's surname to the ballot paper without nominations from at least 50 members of parliament.
"Accordingly, the Judge accepted that the decision of the NEC [the National Executive Committee of the Labour Party] was correct and that Mr Corbyn was entitled to be a candidate in the forthcoming election without the need for nominations," the ruling published on the Judiciary of England and Wales government website said.
The Labour leader has already welcomed the court's decision.
"I welcome the decision by the High Court to respect the democracy of the Labour Party… There should have been no question of the right of half a million Labour Party members to choose their own leader being overturned," Corbyn said, as quoted by The Guardian.
In June, Corbyn faced a motion of no confidence and saw half of the shadow cabinet resign in protest at what they claimed was his inability to lead the main opposition party after the Brexit referendum. Corbyn refused to resign and said he would take part in the party leadership election due to take place on August 22.
