Can you break the law to stop climate change … and get away with it?
That’s exactly what five climate change activists wanted to argue at a
recent criminal trial in Seattle, Washington.
In September 2014 the group tied themselves to a 25ft (8 metre) high
“tripod” over a railway line in Washington State, US, to block a train
carrying crude oil which, if used, would have contributed directly to
carbon emissions and so climate change. The activists, now known as the “
Delta 5”, relied on the so-called “necessity defence” to justify their actions and avoid criminal liability.
A successful “necessity defence” needs to show that the crime was
necessary in order to prevent an even greater criminal act or
irreparable evil. There should be no reasonable legal alternative
available under the circumstances. In court, the Delta 5 argued that
their actions to prevent the oil from reaching its destination were
necessary to stop the greater harm of climate change. As such, they said
they shouldn’t be held criminally responsible.
The activists hoped to set a new precedent in the United States which
would have paved the way for climate activists in the future to more
readily use necessity as a defence to criminal charges. In 2008, for
example, a group of six Greenpeace activists were tried in the UK for
property damage and trespass after shutting down a coal power station.
They used the necessity defence and were
acquitted by a jury.
The judge in Seattle, however, ruled that the defendants had failed
to show that there was no reasonable legal alternative to their actions.
Even though the judge was sympathetic to the activists cause, she was
bound by
case-law
on the lack of evidence supporting a necessity defence and reluctantly
instructed the jury to ignore all wider arguments about climate change.
The five were found guilty of
misdemeanour trespassing.
Legal recognition for “necessity” remains a long-term goal for
climate activism, but the latest setback shows how difficult these
arguments are to win in court. It’s not just climate change. Attempts to
justify the use of marijuana for medical purposes have been met with mixed success, where successful necessity defences have been very much
the exception rather
than the rule.
Necessity has been most successful in cases involving
potential crimes by doctors
around the issue of consent, but there are major limits. It’s usually
not recognised as a defence against murder charges, for example, a view
that dates back to the 1880s when two shipwrecked sailors decided to
kill and eat their subordinate, a cabin boy, for survival when lost at sea.
Playing by the rules isn’t working
While necessity is difficult to assert in climate activism trials,
the Delta 5 and Greenpeace cases raise a big question: should activists
be allowed to take matters into their own hands to prevent global
warming and climate change? Given underwhelming results in combating
this at the international level to date, arguably they should.
The Paris climate change agreement in December was celebrated as a
major achievement in bringing all states together, developed and
developing alike, to agree on a common plan to reduce global carbon
emissions. However, on closer inspection, it doesn’t seem to be
ambitious enough to work as expected. Warming will be
limited to 2.7°C, at best, while the agreement isn’t yet
legally-binding. Climate change is still likely to have
severe effects.
Robust action – without fear
If states are unwilling or unable to sufficiently reduce their carbon
emissions in time to make a real difference, shouldn’t people around
the world be encouraged to take robust action without fear of being
thrown in jail for their efforts to do good?
Since the 1950s legal theorists have argued about the consequences
for people who feel morally compelled to break the law. The so-called
“Hart-Fuller” debate, which continues to divide legal scholars
to this day,
examined among other things the nature of laws in Nazi Germany – for
example, was legislation which authorised the transportation of Jews to
concentration camps
valid law at the time?
The prominent legal philosopher HLA Hart argued yes: he believed laws
continue to have legal force, despite a questionable moral basis. Lon
Fuller, his rival, said that laws have an inner morality, without which
there is nothing to be enforced or obeyed as “law”.
Fuller’s position may provide moral guidance to climate activists who
perceive as immoral the legal framework currently configured to see
global temperatures far exceed the 2°C limit. They can use society’s
understanding of what the law ought to be – one that protects the
environment – to justify their decision to disobey.
Hart would say that the law should not be disobeyed despite its
questionable moral basis because to do so may open the door to anarchy
and conflict. However the necessity defence falls squarely within the
letter of the law, and therefore Hart’s theory, though it remains
notoriously difficult to prove. Climate activists should bear in mind
that they will need convincing proof of no reasonable legal alternative
to their actions in order to increase their chances of success when
raising necessity as a defence in future criminal trials.
The best way for climate activists to do this would be to leverage
conventional legal and political routes as much as possible to achieve
their goals. Once all of these options have been exhausted, then there
may be no further reasonable legal alternatives left and as such, acts
of civil disobedience which break the law may more easily be justified
as being necessary. But as yet, strategies that draw upon Fuller’s
theory of the inner morality of law, to justify disobeying the law
regardless of reasonable legal alternatives, may not help activists keep
a clean criminal record.
It is quite clear that necessity isn’t a reliable defence against
criminal charges at present. But more sympathetic judges and juries in
the future may radically transform the odds of success. The judge in the
Delta 5’s case was sympathetic, though it didn’t lead to their
successfully defending their position. As the effects of climate change
become more and more noticeable, perhaps there will be no reasonable
legal alternative in the future but to follow in their footsteps. The
law just might keep pace.
