On 6 February, the European Court of Justice issued its ruling in the Altun case (C-359/16) relating to fraudulent E101 certificates (documents stating which national social security legislation applies to the holder, now known as A1 certificates). The ECJ held that the courts of a host Member State are not bound by an E101 certificate when it is established that the certificate was fraudulently obtained and the sending state failed to carry out a review of the certificate’s validity within a reasonable period of time.

Background

In this case, several Bulgarian companies posted employees to Belgium. The Bulgarian companies in question had hardly any activities in Bulgaria; meaning one of the conditions for E101 certificates to be validly granted was not fulfilled. Despite this, their employees were subject to Bulgarian social security and were in possession of E101 certificates.

A request addressed to the Bulgarian authorities to cancel the E101 certificates was not adequately dealt with. As a result, the Belgian authorities took legal action to make the employees subject to Belgian social security. As part of this process, a preliminary question was put to the European Court of Justice concerning the binding power of a fraudulently obtained E101 certificate.

The Court’s findings

The Court of Justice recognised that ‘fraud corrupts all’ (i.e. fraud invalidates all aspects of a decision) is a fundamental principle of EU law. According to the Court, a finding of fraud requires both an objective and a subjective element:

• the posting conditions are not in fact fulfilled, and;
• the failure to meet these conditions is deliberately hidden by the people concerned (e.g. by misrepresenting the situation or by withholding relevant information).

If the sending state fails to address a request to reconsider the E101 certificate adequately, a judge in the host state establishing fraud can disregard the certificate. However, the Court underlined that when establishing fraud, the judge must safeguard the rights of defence of the parties concerned.

From now on…

Following this ruling, courts in the host Member State will be entitled to hold that workers posted from other Member States are subject to the host’s social security regime if they establish fraud and the sending state has failed to reconsider the A1 certificates.
