very concerning how the MHA/DOLS can be used to authorise completely inappropriate placements for young people especially. you may find interesting Launch of National Deprivation of Liberty (DoLs) Court at the Royal Courts of Justice - https://www.familylawweek.co.uk/site.aspx?i=ed229970. From 4 July 2022, all new applications seeking these orders will be issued in the Royal Courts of Justice (RCJ).
Not my area of expertise but i found these interesting reads:
