The concept of ‘working time’ for a period of stand-by time according to a stand-by system applicable to firefighters was interpreted by the Court in MG (C-214/20). In the Y case (C-636/19), the Court interpreted the concept of ‘insured person’ for the purpose of reimbursement of healthcare costs under Directive 2011/24. In the TS case (C-538/19), the Court dealt with another cross-border healthcare case. This time the question was whether a Member State can require an authorisation for cross-border healthcare to be subject to the submission of a medical report drawn up by a doctor from its national public health insurance system in light of Article 20 of Regulation 883/2004 and Article 56 TFEU. In ASGI and APN (C-462/20), the exclusion of third-country nationals from the eligibility to the Italian family card was under scrutiny. In SC (C-866/19), the Court clarified that the principle of aggregation applies to the calculation of the theoretical amount of benefit but not to the calculation of the actual amount of benefit under Article 52(1)(b) of Regulation 883/2004. In K (C-285/20), the Court held that being on sick leave and receiving sickness benefits can be considered as equivalent to the pursuit of an economic activity for the purpose of applying the rules on unemployment benefits for wholly unemployed frontier workers under Article 65(2) and (5) of Regulation 883/2004.
