The act applies only to ‘protected’ animals which means animals of a kind commonly domesticated in the UK and/or those under the control of man or “not living in a wild state”.
So all of what you quoted does not apply to ‘wild’ animals.
Which leads me to suspect one of the reasons for not including the requirement was… fox hunting.
Yet again. For some reason the conservative party has an obsession with removing the ban on hunting with dogs.
Which is an odd thing because all the people I know who actually go hunting couldn’t care less about the ban on hunting with dogs being repealed. They’ve quite happily accommodated themselves to the new legal landscape and don’t really want to go back to the previous set-up.
For those interested in the actual debate in Parliament:
starting at column 471, 7:00pm.
It contains this wonderful bit of arse-creepery:
Summary
Sir Oliver Letwin
Well, we must leave it to Ministers to speak for themselves, but I have to say that the discussions that I and others had with the Secretary of State, who, as people have remarked in this debate, is of a very different cast of mind from some previous Secretaries of State, suggest to me that actually there will be an environmental protection Bill coming forward. I think that is—[Interruption.] Ah! Maestro! With perfect timing my right hon. Friend the Secretary of State comes into the Chamber, at just the right moment for him to signify with a nod, if nothing more, that the possibility of proper environmental legislation in the form of a new statute is on his mind.
The Secretary of State for Environment, Food and Rural Affairs (Michael Gove)
indicated assent.
Sir Oliver Letwin
And his mind is one that is capable of grasping these matters, if ever the mind of a Member of the House of Commons was. The first point, then, is that a proper statutory basis is superior to a specific amendment to the Bill.
Bear in mind this is Michael Gove he is talking about…
So, the argument in Parliament is that the EU Repeal Bill is not the place to enshrine this protection because:
a) domestic law already does (well, no it doesn’t.) and/or;
b) the right place to do it is in a separate environment bill where it can be debated properly. (Because of course recognising the sentience of other beings is something that really does need several hours of intense debate.)
and not at all to do with keeping the barriers to removing/reducing environmental protections as low as possible. /s
