There are two contexts in which this story can be analyzed: 1) the futility of trying to use the courts to attack or quash negative reviews and 2) European courts’ increasingly bold attempts to blunt the impact of or censor specific search results that are perceived to cause harm (whether or not the information at issue is truthful or factual).
On the first point the restaurant has gained much more unwanted attention for itself through the action and subsequent coverage. I wouldn’t be surprised now if it went out of business. However, the food and service appear to be mediocre; so perhaps it’s inevitable anyway.
On the second matter, I’m sure the BBC coverage fails to elucidate some of the nuances of the case but the judge’s actions and decision appear to me to be pretty outrageous. I could perhaps understand the decision if the review were totally defamatory and not supported by the weight of opinion from other sources. But it seems very consistent with other reviews.
The only “crime” here, then, was ranking too high in search results.
