The legislature declares that the changes to the maximum percentages of earned release time in chapter 379, Laws of 2003 do not create any expectation that the percentage of earned release time cannot be revised and offenders have no reason to conclude that the maximum percentage of earned release time is an entitlement or creates any liberty interest. The legislature retains full control over the right to revise the percentages of earned release time available to offenders at any time. This section applies to persons convicted on or after July 1, 2003.
