Hirst v United Kingdom (No 2) (2005) ECHR 681 is a European Court of Human Rights case, where the court ruled that a blanket ban on British prisoners exercising the right to vote is contrary to the European Convention on Human Rights. The court did not state that all prisoners should be given voting rights. Rather, it held that if the franchise was to be removed, then the measure needed to be compatible with Article 3 of the First Protocol, thus putting the onus upon the UK to justify its departure from the principle of universal suffrage.

Anti‑protest regulations (Liberty v Home Secretary)

Air pollution litigation (ClientEarth v UK Government)

Windrush - Members of the Windrush have repeatedly challenged the Home Office over wrongful detention, removal, and denial of rights, leading to government admissions of unlawfulness and an official apology in 2018.

Your claim is false. The world is not the same the world over, civil liberties are better in some places than in others.
