The law also says a counter claim can be immediately filed. Google don’t follow that part.

Google has nothing to do with filing a counter claim except accepting it if filed. The content owner is the only one who is allowed to file it.

Google do not immediately reinstate on counter claims.

They shouldn’t, because the original claimant has 10-14 days (depending on exact timing) to sue. If they don’t, they reinstate. Which considering many other folks it can take 6 months…

Not saying Google is good or anything, but this is well trod ground at this point.
