Over the last decades, both states and intergovernmental organisations have increasingly adopted restrictive legislation and guidelines in an attempt to combat or counter terrorism. Reports from humanitarian organisations about the disastrous consequences of these counterterrorism measures and sanction regimes on their daily work, especially within conflict settings, are growing. However, the complexity and sensitivity of this topic complicate the urgently needed exchange between humanitarian organisations as well as the exchange between organisations and donors. Both perspectives require a sincere and transparent debate on the negative impact of counterterrorism legislation and sanction regimes on humanitarian action, which first and foremost aims to protect the well-being of an affected population and the humanitarian space as a whole. This contribution will therefore set out the current state of the debate in order to stimulate further exchange on this topic.
