It says there will be no more industrial action from ASLEF, which is contrary to what people stated earlier that the industrial action will continue. Or are we saying that the RMT will continue striking but ASLEF won't?
ASLEF have been told that their actions in telling drivers not to drive 12-car DOO(P) trains on Gatwick Express is likely to be interpreted at trial as them inducing their members to strike illegally. There were separate issues about some of the depots ASLEF chose to ballot, where GTR said that although hypothetically the drivers could have to drive DOO(P) on Gatwick Express, in reality they wouldn't, and so shouldn't have been balloted. Justice Supperstone sided with GTR, and found that the ballot was flawed because GTR said they wouldn't have to drive DOO(P) on GatEx and ASLEF's separate professional advice was an "inducement to strike".
I think the court's interim decision meant that the chances of winning a trial were very slim, and it was better to cut one's losses.
The RMT, as a separate trade union, are not bound by anything ASLEF agree. However it does undermine their strike action as, should GTR force through the changes, strike action will not prevent services from running.
As an aside, Justice Supperstone has a long history of anti-trade union judgments, including a recent case where he found that people in the construction industry who had illegally "blacklisted" union members should not be tried at criminal law for their actions. His rationale was that they'd said sorry so they shouldn't face criminal sanctions for their 40 years of illegal blacklisting.
