The Case Law is explained in our PIP Claim guide in the section for the activity.
I need to correct your understanding of the UTT Decision as expressed in the above post.
It does not say "instead of 2 points everyone should have had 4 points for engaging with people", rather it says that claimants who meet specific criteria may have scored four points rather than the two previously awarded.
It is down to you to show that you meet that criteria.
