Or reduce the demand on the legal system? Just adding more expense to an outright broken thing isn't an actual fix. It's a half-measure patch at best. And no, I don't mean create a workaround like arbitration.

Why do court cases take so long and suck up so many resources? Start with that. Perhaps reduce the amount of legislation/laws/etc. on the books, and write laws that limit the litigious society we find ourselves living in.

That is of course easier said than done, but we've chosen this path and can choose to unwind it if we have enough desire to.
