Snooker's governing World Professional Billiards and Snooker Association stated:
"The WPBSA has been informed by the Gambling Commission that the CPS will not be taking further action in relation to the match-fixing allegations against Stephen Lee, made in 2010.
"The Commission has decided not to commence criminal proceedings under the Gambling Act 2005.
"The WPBSA will now be allowed access to details pertaining to the enquiry in order to consider whether there has been a regulatory breach of the Governing Body's rules."
Lee, 37, turned professional in 1992 and has won five ranking events including the 2012 Players Tour Championship finals.
He was a semi-finalist at the 2003 world championship and moved up to number six in the world last week after winning the second Asian PTC event in China.
Lee was arrested at his Wiltshire home in February 2010 and bailed.
