The "responsible authority" is defined in rule 1 of Tribunal Procedure (First-tier Tribunal) (Health, Education and Social Care Chamber) Rules 2008 as follows:
“responsible authority” means—
- (a) in relation to a patient detained under the Mental Health Act 1983 in a hospital within the meaning of Part 2 of that Act, the managers (as defined in section 145 of that Act);
- (b) in relation to a patient subject to guardianship, the responsible local social services authority (as defined in section 34(3) of the Mental Health Act 1983);
- (c) in relation to a community patient, the managers of the responsible hospital (as defined in section 145 of the Mental Health Act 1983);
The definition in Rule 2 of Mental Health Review Tribunal for Wales Rules 2008 is materially the same.
