Each provision of this FWC is severable and distinct from the others. If a provision is or  becomes illegal, invalid or unenforceable to any extent, it must be severed from the remainder  of the FWC. This does not affect the legality, validity or enforceability of any other provisions  of the FWC, which continue in full force and effect. The illegal, invalid or unenforceable  provision must be replaced by a legal, valid and enforceable substitute provision which  corresponds as closely as possible with the actual intent of the parties under the illegal, invalid  or unenforceable provision.
