Delhi's Lt Governor Anil Baijal had on Wednesday granted three weeks parole to Ajay Chautala, who is serving a 10-year term in connection with teachers' recruitment scam in Haryana.
Dushyant Chautala's wedding is scheduled for April 10.
Ajay Chautala through his lawyers had filed a petition in Delhi High Court seeking parole to attend the wedding and other customary obligations.
The INLD leader is expected to be released after formalities are completed and bail bond furnished, said his lawyer Amit Sahni.
In the plea, Mr Chautala said he had applied for grant of parole before the Tihar Jail Superintendent on February 14.
The High Court had asked the Delhi government to decide on it within 30 days.
Ajay Chautala and his father O P Chautala are serving 10-year jail terms each in the junior basic trained (JBT) teachers' recruitment scam case.
The father-son duo and 53 others, including two IAS officers, were convicted on January 16, 2013 by the trial court for illegally recruiting 3,206 JBT teachers in Haryana in 2000.
