I wonder how many stories like this are caused simply because a corporate lawyer is looking for some work to do, and maybe to meet some kind of internal KPI.
Is it the job of an in-house lawyer (or any lawyer) to say that this appears to be a vexatious or SLAPP case, and the client should not pursue it?
Is there an ethical obligation not to get involved in a case that you know is being prosecuted in bad faith?
The bar there is very high. This case might be embarrassing but probably isn’t sanctionable. And the only lawyer that would get sanctioned would be the ones that signed the papers not the drone that hired them.
