BBC: Two pressure groups have won a High Court challenge on the legality of the decision to end investigations into BAE Systems' dealings with Saudi Arabia.
Corner House Research and the Campaign Against Arms Trade (CAAT) had asked for permission to seek a judicial review.
They want to contest the Serious Fraud Office's decision last year to stop investigations into whether BAE gave money to Saudi officials in the 1980s.
BAE, the UK's largest defence group, has always said it acted lawfully.
Lord Justice Moses, sitting with Mr Justice Irwin, said "matters of concern and public importance" had been raised and the challenge "cries out for a hearing". Court to study BAE fraud decision (more)
