The International Cricket Council approved its revised anti-corruption code on Monday but left it up to home boards to allow banned players to return early to domestic competition.
For a player to return to domestic competition before the expiry of his ban would need the agreement of the chairman of the anti-corruption board, Sir Ronnie Flannagan, and the relevant National Cricket Federation, with the approval of the ICC Board, an ICC release explained.

The revised code will specifically help Pakistan seamer Mohammad Amir's early return to domestic cricket, likely in February next year.
Last year, the Pakistan Cricket Board had demanded the ICC relax certain conditions of Amir's ban after he pleaded guilty to a spot-fixing crime and then completed the rehabilitation process.
Amir, now 22, was banned along with Salman Butt and Mohammad Asif in a spot-fixing scandal on Pakistan's tour of England in 2010.
Amir was banned for five years, Butt for 10 (with five suspended) and Asif for seven (two suspended).
The trio, also jailed in Britain, were charged with orchestrating deliberate no-balls during the Lord's test against England in return for money.
The ICC said the revised code would close certain loopholes and address the issue of who has jurisdiction in a particular case.
The code would also allow a player charged with an offence but who has not been provisionally suspended, to agree to voluntarily suspend him/herself, the ICC said.
ICC chairman Naryanaswami Srinivasan, himself suspended in India over a fixing scandal in a Twenty20 league, said: "The process for the revision of the ICC Anti-Corruption Code was exhaustive and has been based on our learning and experiences over the past few years.
"This code is now even more robust and comprehensive and it provides clarity on jurisdictional issues, gives options to the charged participant and offers more choices to the Anti-Corruption Tribunal."
ICC Chief Executive David Richardson admitted the fight against corruption was still a priority.
"The battle against corruption remains one of cricket's biggest challenges and we remain committed to eliminating this menace from our sport," he said.
Amir last week told AFP that he was anxiously awaiting the revision of the code and would apply to the Pakistan Board to be allowed to play in domestic matches.
"I am waiting for the ICC decision and once it comes I will apply with the PCB to resume my domestic career and then international matches," said Amir.
