Throw the team under the bus

Maybe this Joey is a bcc, blindly creating chaos.

Got a blanket mail from the PM no impact, no CR required, forget about it.

Use that to your advantage and challenge it, where is his CAB sign off to support his statement.
Typically only a Change Manager or the CAB should be asked to determine that, but then I come from an Avionics background where proper Change Control mattered.

Sadly PMs especially in IT often think they personally can determine what does and does not constitute a change especially if their piss poor planning meant they forgot to factor in the change approval leads times so are now cutting corners

Are any of the team members actually a young kangaroo? That might explain the nickname Joey.
