This FTA is between the UK and Australia. I'm under the impression that both the UK and Australia currently have laws allowing them to comply with this agreement, so adding a requirement like this wouldn't change anything here.
It does change something. It makes it much harder for that law to be changed in future.
The judicial system is constitutionally required to ignore it. The legislature is mostly controlled by the executive. And the executive only respects international agreements when they are convenient.
> must pass all the laws needed to comply with that agreement ahead of time
Which is already met, so it wouldn't change anything.
I can't get to torrent search engines in the UK. I double click Nordvpn.com/bigmoney and then click "connect". I can now get to the torrent search engine without issue, even while connecting to a UK node....
Its a lot of words to add maybe three seconds of delay to my web browsing experience.
