“In Animal Defenders International, the European Court of Human Rights upheld the British ban on political advertising in the broadcast media (s.321 Communications Act 2003), consistently with the judgments of the UK House of Lords and High Court, but in an apparent departure from its previous caselaw in the VgT (Verein gegen Tierfabrik v. Switzerland, no. 24699/94 ECHR 2001‑VI) case. The key issue in the case was whether a blanket ban (or ‘general measure’) was a proportionate restriction of the freedom of expression, or whether some class of exception (a ‘case-by-case’ approach) for groups such as the NGO in this case ought to be recognized.”
