Facebook informs the Irish court that its EU operations are challenged by probes.

Facebook told the High Court of Ireland that it did not see how its services did work in the European Union if regulators were to freeze their data transfer process, the Sunday Business Post reported, citing the paper’s court documents.

Last week, the U.S. social media giant said that its lead EU regulator, the Irish Data Protection Commission, had made a tentative decision that the system it uses to move data from the EU to the United States “will not be used in practice.”

In the Irish High Court, which is due to consider the issue in November, Facebook sought and secured a freeze temporary on the order and a court review.

The Sunday Business Post reported that in an affidavit submitted to the court demanding that the order be frozen, Yvonne Cunnane, Ireland’s Facebook head of data security and associate general counsel, said that it was not clear how the company will continue to provide services in the EU if the Irish order were implemented.

“It’s not clear for (Facebook) how it will continue to provide the Instagram and Facebook services under the EU in those circumstances,” the newspaper reported the affidavit as saying.

The affidavit was not made public, a spokesperson for the High Court said, and a Facebook spokeswoman did not respond to an emailed request for clarification immediately.

In a blog post on Sept. 9 that first announced the Irish regulator’s inquiry, Facebook said it “relies on the system in question to move data to countries outside the EU under what are recognized as standard contractual clauses (SCCs) and that a ban would have” a far-reaching impact on companies that depend on SCCs.

The Irish investigation follows a European Union Court of Justice decision in July on what legitimate use of SCCs can be made.

The ruling came in response to EU fears that the U.S. surveillance system may not value EU citizens’ privacy rights when their personal data is exported for commercial use to the United States.
