Justice Vipin Sanghi ordered Chautala's release for a day on his furnishing a bond of Rs 50,000 and directed the INLD leader to surrender on January 4 at 11 AM.
The court said it will hear Chautala's main petition against the Delhi government's December 14, 2016 decision dismissing his plea for six months' parole on medical grounds, on January 17.
The Delhi government opposed the grant of interim parole saying Ajay Chautala, also a convict in the case, was already out on parole to attend the marriage function of his son Dushyant.
Sahni, however, said that as per the parole norms, under special circumstances like in the instant case, two convicts of a case can be granted the relief simultaneously.

In his main plea, O P Chautala has contended that the Delhi government's December 14 decision was passed in "an extremely unfair manner upon flimsy grounds".
He said he was on bail during the trial and was released on parole, but he has never misused the same.
Chautala, his son Ajay and three others are serving 10-years jail term in the case.
The Supreme Court on August 3 last year had dismissed the Chautalas' appeals against the high court's verdict upholding their conviction and sentence of 10 years awarded by a trial court in the junior basic trained (JBT) teachers recruitment scam case.
The high court had on March 5, 2015 upheld the 10-year jail term awarded to Chautalas and three others, saying, "The overwhelming evidence showed spine-chilling state of affairs in the country."
