Quoting from the press release, the data exporter must take into account both the contractual clauses AND the surveillance laws of the target country. It is not sufficient to rely on a contract with a US data processor where the US surveillance laws do not make it possible for the recipient to comply with that contract.
> In those circumstances, the Court specifies that the assessment of that level of protection must take into consideration both the contractual clauses agreed between the data exporter established in the EU and the recipient of the transfer established in the third country concerned and, as regards any access by the public authorities of that third country to the data transferred, the relevant aspects of the legal system of that third country.
> [...] that
decision imposes an obligation on a data exporter and the recipient of the data to verify, prior to any transfer, whether that level of protection is respected in the third country concerned and that the decision requires the recipient to inform the data exporter of any inability to comply with the standard data protection clauses, the latter then being, in turn, obliged to suspend the transfer of data and/or to terminate the contract with the former.
