Overview
Eléonore Mullier specializes in EU regulatory law and litigation. She advises clients who, whether based in the EU or not, come into contact with EU regulations affecting the placing on the EU market of their products. Eléonore's knowledge extends to the entire life-cycle of materials, from chemicals legislation (biocides, REACH, classification and labelling, plant protection products, POPs, PPPs, etc.) to product and waste legislation (CE marking, RoHS/WEEE, Ecodesign, medical devices, single use plastics, waste and end-of-waste). She also advises clients on the interface between these regulations and on cross-sectoral issues including the European Green Deal initiatives such as the Chemicals Strategy for Sustainability, the Sustainable Products Initiative and the corporate sustainability initiatives.
Quoting clients and peers, Chambers Europe highlights that Eléonore has “very strong communication skills” and “provides advice which is easy to understand and to translate into business practices, while also remaining within the realms of what will be accepted in the regulatory arena."
In the REACH and CLP area, she advises clients on all aspects of compliance including on authorization, dossier and substance evaluation, intermediates, restrictions and data sharing, as well as harmonised classification and labelling. She also advises on emerging issues such as the developments under the Chemicals Strategy for Sustainability, the regulation of PFAS and the revisions of the REACH and CLP regulations.
In the biocides area, Eléonore advises clients on all aspects related to getting and keeping substances and products on the market. She assists clients with issues related to active substance approvals, biocidal product authorizations including biocidal product families and same biocidal product authorizations, and related data sharing, consortium and contractual advice.
Eléonore also has extensive experience representing clients before the European Court of Justice and the ECHA Board of Appeal and before both national and EU regulatory authorities (the European Chemicals Agency, the European Commission, and national competent authorities).
Eléonore is a frequent author and speaker at conferences. She sits on the editorial board of the International Chemical Regulatory and Law Review and is member of the Women's Law Network.
