Ajit Singh, chief of the anti-corruption unit of the Board of Control for Cricket in India, lauded Britain's extradition of accused match-fixer Sanjeev Chawla.
Chawla is one of the key figures named in the 2000 match-fixing scandal surrounding former South Africa captain Hansie Cronje.
Chawla spent four years evading extradition and was finally sent back to India on Thursday where he will be tried by the Delhi police crime branch.
The 50-year-old, known for his activities in the cricket gambling underworld, had a chargesheet filed against him in 2013.
The co-conspirator was arrested in the UK in 2016 and subsequently extradited after the European Court of Human Rights rejected his appeal last week.
On the orders of a Delhi court, Chawla will be held in custody for 12 days for questioning though he has challenged this decision at the High Court.
"It is a legal landmark," Singh told AFP of the latest legal outcome.
"Extradition is a difficult process. All sorts of objections were raised, to the extent of threat to life of the accused and even the conditions of the Indian prisons.
"And this one is the first for match-fixing."
Singh said the BCCI would also seek permission to interview Chawla as he had asked Indian police "to share anything, any information pertaining to cricket given to the police by Chawla."
Indian cricket has recently seen the unravelling of the Karnataka Premier League fixing scandal, which has resulted in the arrests of six individuals including two former Indian Premier League players.
Cronje's illegal contacts with the bookies were uncovered when Delhi police was investigating an unrelated extortion case in early 2000.
The shocking revelations later made by Cronje in a tearful submission to an inquiry in South Africa rocked the cricketing world.
The disgraced captain was banned for life while teammates Herschelle Gibbs and Henry Williams received six-month suspensions. Cronje passed away at the age of 33 in a plane crash in 2002.
