The Supreme Court has overturned a High Court ruling that the rent payable by the Bewley's on Grafton Street must be allowed to fall to reflect market levels.

Bewley’s victory in the High Court is unlikely to help tenants struggling with upward-only rent reviews, says NUI Galway lecturer in land law, Padraic Kenna.
