1.4 The right to interpret this rule belongs to ISAF, and IMCO should be consulted when making decisions.

1.5 Modifications to this rule will be submitted for review by ISAF after being approved by a majority vote at the IMCO Annual Meeting. IMCO and Michaels Sports have equal voting rights on proposed rule changes. The revised rules will not take effect until approved by the IAF.
