It looks like they were serious after all. I must admit I was beginning to doubt them, but according the Irish Echo, the Daily Ireland (by which presumably they mean its principals) has issued its much anticipated writ against the Minister for Justice. Given that the case could presumably have been brought in the Republic, some may find their faith in British justice particularly heartwarming.
The article goes on to describe the paper’s circulation as “far more than its detractors had anticipated and indicative of its long-term commercial potential”. Having come close to a similar experience themselves, the Echo is clearly taking no chances this time.
