Thieffry v Conseil de l’Ordre des Avocats à la Cour de Paris Case 71/76, [1977] ECR 765
Facts
Jean Thieffry was a Belgian lawyer who wished to practise in France. A French university recognised his Belgian legal diploma as equivalent to the relevant French degree, and he obtained the French certificate of aptitude for the legal profession. Admission to the Paris Bar was nevertheless refused because he did not possess the specified French diploma. The dispute raised whether the academic recognition already obtained could be disregarded for professional admission. The national proceedings led to a reference on freedom of establishment and recognition of qualifications.
Legal Issue
Could the host state refuse professional admission solely for lack of a domestic diploma after recognising an equivalent foreign qualification and permitting completion of its aptitude requirements?
Held
The Court held that a refusal based solely on the absence of the domestic diploma could constitute an unjustified restriction on establishment in the circumstances. Thieffry’s foreign qualification had been recognised as equivalent and he had satisfied the relevant professional aptitude requirement. The absence of a complete Community system of diploma recognition did not allow the Treaty freedom to be disregarded. National authorities had to use their powers consistently with that freedom and the recognition already granted. The ruling did not equate every academic recognition decision with an unconditional right to practise; the applicant’s complete qualifications and the professional requirements he had met were central.
⭐ Legal Principle
Where host-state authorities have recognised equivalent foreign qualifications and the applicant has met the relevant professional aptitude requirements, refusing admission solely for lack of the domestic diploma can unjustifiably restrict freedom of establishment.
Significance
Thieffry shows how the Treaty can require meaningful recognition before a complete legislative harmonisation scheme exists. Vlassopoulou later developed the duty to compare qualifications and experience. The case is not a general rule that any foreign degree automatically gives access to a profession. The nature of the recognition and the additional professional conditions must be established on the facts of the particular application.
Common exam questions about this case
Why was Thieffry’s professional aptitude certificate important?
It showed that the applicant had satisfied a further host-state professional requirement, in addition to obtaining recognition of his foreign diploma. The refusal therefore rested on formal possession of the French degree rather than an identified competence gap. Those combined facts limit how broadly the judgment should be stated.
Did the lack of a harmonising directive defeat the Treaty claim?
No. The freedom of establishment still constrained national authorities in exercising their powers. A legislative recognition framework could facilitate mobility, but its absence did not justify disregarding recognised equivalence. The Treaty analysis focused on whether the particular refusal created an unjustified obstacle to professional practice.
How does Thieffry relate to Vlassopoulou?
Thieffry concerns the effect of recognition and professional conditions already satisfied. Vlassopoulou explains the broader obligation to compare foreign qualifications and experience with domestic requirements. Together they support an assessment of actual competence, while preserving proportionate steps to address genuine differences in professional knowledge.
