xsd:string A particular Binding_principle is (or is not) operative, that is, any obligations, restrictions, and any other aspects of the Binding_principle are (or are not) in effect. The Binding_principle can be expressed as being in effect for a particular Duration, or at a particular Time or Place, or under certain Circumstances. This law will only become in effect during the last three weeks of the year. The statutory wetlands definition is effective immediately. This contract is binding on all parties. Although the in effect is properly in this frame, (put) into effect is analyzed in the Execute_plan frame. This is in part because to put an (evacuation) plan into effect is to actually execute the plan (to evacuate), while to put a plan in effect is to determine that in the future the plan may have to executed, i.e., to make the plan binding. Similar observations can be made for come into effect.
