“Can you hear the future weeping? Our love must save the world.” So ended Morgan Trowland’s closing address to the jury, in the trial for Public Nuisance that followed his and Marcus Decker’s “Just Stop Oil” protest last year on the Dartford Bridge. The Ben Okri quote was a nice finish to a well-delivered speech. Even as the prosecutor, I felt the force of the sentiment.
It had been an unusual trial. In protest cases, it is not uncommon to find defendants who choose to go without an advocate, since those defending themselves are, quite rightly, given a little more latitude than lawyers. Usually, protesters’ evidence about their beliefs is kept short, for the sake of time and simplicity, or even proscribed altogether, when the limits of any “reasonable excuse” defence can easily be determined in advance. But the defendants here, with the agreement of all parties, were allowed to explain their motivations at considerable length. The jury heard nearly four hours of evidence about the science of climate change, its consequences, and government policy.
All of which turned out to be, strictly speaking, irrelevant. Because once the evidence had been heard, the court decided that, on all the facts of the case, the “reasonable excuse” defence did not allow for a protest at the top of this bridge.
The right to protest is an important one, protected first by our Common Law and then by the European Convention. But there must be limits, even where no violence is used and no damage caused. Those limits in the British courts, though, are surprisingly hard to discern.
At least part of the reason for the judge’s ruling was that the public has no general right to access the Dartford Bridge, much less to climb it. Indeed, it is a criminal offence even to walk onto it. For protests on other roads, a jury might, depending on circumstances such as how long the disruption lasts, be told that the question of reasonableness is up to them.
Nevertheless, the unrepresented defendant was not prevented from asking the jury to find that their actions were reasonable — and so I was not prevented from arguing that they were not.
