SLAPP as in Strategic Lawsuit Against Public Participation.
To keep the dissenting voices quiet and to scare other groups from protesting.
Modus operandi for many industries.
That is objectively not what happened here though, the point of SLAPP is that it's a frivolous suit that's meant to just exhaust the resources of the "dissenting voices". They won this suit and honestly it's not hard to believe that Greenpeace is guilty to some degree even if proving it is.

Unfortunately North Dakota is one of the minority of states without anti-SLAPP laws.
A SLAPP is a frivolous lawsuit that the plaintiff has no chance of winning. In this case they won a judgment, so it's the opposite of that.
