  • Acting at trial, instructed by a local authority, in a case considering the best interests of an elderly woman whose husband believed she should return from a care home to live with him. There was a background of safeguarding issues including allegations of coercive control. The Judge determined that it was in P’s best interests to remain in residential care.
