2013/47 When is employment “genuine” for social security purposes? (PL)
The social security institution of a Member State may not determine on its own whether the employment of one of its residents in another Member State is genuine. It should rely on the decision of the institution of that other Member State or adopt the procedure provided in Regulation 987/2009.
