From IRB website
The global trial of the IRB Experimental Law Variations (ELVs) starts on August 1, 2008. However, due to the fact that the southern hemisphere season commenced in February there are some southern tournaments that are trialling more than the 13 ELVs that have been approved for global trials from August 1.
Special dispensation has been given to the southern hemisphere Unions to continue the more extensive ELV trials that are already in place. These tournaments will come in line in with the global trial at the start of the next southern hemisphere season.
The IRB will convene a meeting with representatives from the IRB Law Project Group, Executive Committee and Union representatives in March 2009 to begin a full review of the ELV programme and to recommend to the IRB Rugby Committee which ELVs, if any, should be adopted into Law. The Rugby Committee will then report to the IRB Council and in July 2009 the IRB will determine one set of uniform Laws that will be played globally from August 2009 onwards.[/b]
