Solicitor Tessa Gregory, who represented Cait Reilly and 40-year-old unemployed HGV driver Jamieson Wilson, said today's ruling reveals "a lack of transparency" by the Department for Work and Pensions in implementing mandatory work schemes.
The case has revealed that the Department for Work and Pensions was going behind Parliament's back and failing to obtain Parliamentary approval for the various mandatory work schemes that it was introducing.
It also reveals a lack of transparency and fairness in the implementation of these schemes.
The claimants had no information about what could be required of them under the back-to-work schemes.
The Court of Appeal has affirmed the basic constitutional principle that everyone has a right to know and understand why sanctions are being threatened and imposed against them.
