   • 2014 May 20, European Court of Human Rights, McDonald v. The United Kingdom‎, number 4241/12, marginal 48:

     The applicant is therefore complaining not of a lack of action but rather of the decision of the local authority to reduce the care package that it had hitherto been making available to her. As such, a more appropriate comparator would be the case of Watts v. The United Kingdom (dec.), no. 53586/09 of 4 May 2010, in which the Court was content to proceed on the basis that a decision to close the care home where the elderly applicant was resident and to transfer her to another home constituted an interference with her rights under Article 8.

[…] Defendants object to the production of these documents on the grounds that Mr. Lerner is not an appropriate comparator for Ms. Khazarian and his personnel file is therefore irrelevant.
