My eye fell last week-end on The Times of London’s obituary of Sir Peter Singer, z”l , who passed away late in December.
The Times recall among others his linguistic skills and refer specifically to his judgment in  EWHC 49 (Fam) DL v EL, upheld by the Court of Appeal in  EWCA Civ 865. Regular readers will be aware of my interest in languages at the CJEU.
Sir Peter was applying the Brussels IIa Regulation 2001/2003 and had to decide inter alia where the child was habitually residing. In an endnote he discussed C-497/10 PPU Mercredi v Chaffe. At 76 he juxtaposes the English and French versions of the judgment (a technique I insist my students and pupils employ), observing the difference between ‘stabilité ‘ used in the French version and ‘permanence’ in the English, concluding that ‘stability’ would be the more accurate term. The Court of Appeal discusses the issue in 49.
Delightfully accurate and erudite.
