Kolizyjnoprawna problematyka skuteczności przelewu wierzytelności wobec osób trzecich Glosa do wyroku Trybunału Sprawiedliwości Unii Europejskiej z dnia 9 października 2019 r. w sprawie BGL BNP Paribas SA c/a TeamBank AG Nürnberg (C‑548/18)

The question of the law applicable to the third-party effects of assignments of claims is widely discussed in the doctrinal debates. In common opinion, the existing European conflict-of-laws regulations do not provide for a rule governing this issue. In the case BGL BNP Paribas SA v. TeamBank AG Nürnberg (C‑548/18), the Court of Justice of the European Union confirmed this gape of the Rome I Regulation.The gloss presents the justification of the European Union Court’s judgment, the reasons for the lack of the uniform conflict-of-laws regulation, and the consequences of this state. It also analyses briefly the European Commission’s proposal for the EU Regulation concerning the law applicable to the third-party effects of assignments of claims (COM(2018) 96 final), as a response to this situation. Finally, it examines the appropriate conflict-of-laws rules for proprietary effects of assignments of claims (the law of the assignor’s habitual residence and the law of the assigned claim).
