Key legal question
Whether Basel-Stadt could regulate the method for nursing-care needs assessment in nursing homes
Extracted holding
Yes. Federal law had not yet exhaustively regulated the assessment procedure for nursing homes, so cantonal regulation remained permissible.
Extracted reasoning
Art. 25a Abs. 3 KVG delegates regulation of the assessment procedure, but the federal implementing provisions did not set a method for nursing homes; therefore no exhaustive federal regulation excluded cantonal action.
