I should have phrased it better. I am not talking about an arbitration case itself, but the decision to use arbitration as the means for settling disputes. If company decides to use arbitration in 2018, then in 2020, they are not allowed to change their mind to not use arbitration. Deciding to use arbitration locks the company in. Thus, the various arbitration providers don't have any concern that if their decisions are not friendly to the company the company will stop using their services.
This is how every arbitration clause I've seen is structured. I think it's a good idea to write that restriction into law, given anyone deviating from the norm is probably tryin to game the system to their advantage.
This is how arbitration works. Non-binding arbitration is called mediation, and is basically glorified group therapy.
