R (on the application of UK Power Networks Services (Contracting) Ltd) v The Gas and Electricity Markets Authority

Electricity – Supply. The defendant Gas and Electricity Markets Authority decided that the claimant company was subject to the duty to secure access to rival electricity suppliers, under European Parliament and Council Directive (EC) 2009/72 and that the duty could never be shared. The claimant sought judicial review. The Administrative Court, in allowing the application, held that, on the proper construction of the relevant 'system' for the purpose of applying the duty to secure third party access, the Authority had erred in holding that there could only be one distribution exemption holder per network.
