If a MDT is held about a close relative who you advocate for, but you`re not told and left out, is this wrong?
This is a link from 2018. Under the part ’ Can the MDT meeting refuse to proceed if I bring an advocate along?’ Might provide some information for you.
However, it’s a situation where there are many of them and one of you - so you have will have to really put your foot on it and get your input heard for the person you are advocating for.
