Activists have chalked up the world’s first successful legal challenge against police use of automatic facial recognition (AFR) technology, with the Court of Appeal ruling that South Wales Police’s (SWP) use of the technology is unlawful.

The legal challenge was brought by civil rights group Liberty on behalf of Ed Bridges, based in Cardiff. The court upheld three out of the five points raised in the appeal.
