The reason ERAMN fights for the National ERA is because a State ERA will not protect us where there are claims of discrimination by federal agencies, institutions which receive federal funds, or claims against a multi-state private entity. 

In cases where a discrimination case is made against a federal agency, an institution which receives federal funds, or a multi-state private entity, cases will either be brought in federal court or have the federal constitution applied in state courts. 

Also, an ERA victory on the state level with a state ERA will not be precedent for cases in other states. 

So we work together to achieve both a state ERA & a federal ERA – to make equal legal.
