Brooooooooooce:How does this sit with existing cases like Mitchell v HBOS where the Judge made clear the distinction between 'contained' and 'embodied'?

Mitchell v HBOS was a County Court judgement and as such does not set precedent. It can be cited in proceedings as guidance but can be overruled even in another County Court.

If the High Court test cases rule differently to HJ Langan the High Court ruling becomes the precedent.
