I find this both shocking and unsurprising.
More and more bodies that have some kind of public purpose seem to be taking this line - that besides whatever their actual purpose is (providing access to information, doing scientific research, providing drivers licencing services) their other purpose is to 'promote equality, diversity and inclusion when practising or otherwise providing whatever our actually mandated services are".
It seems like all of these people have zero comprehension that if they are there trying to promote DEI activities it might interfere with their actual purpose.
This is why you have people applying for jobs as researchers in universities in sciences or engineering having to justify how they are promoting DEI in their daily work, and the universities and other bodies having to show how each hire fulfills DEI objectives.
In this case, it seems like it could actually undermine actual justice and the principles of serving the client too, which seems to me a little problematic.
