Wow, this is fairly sane and not the murder-people-for-sunbathing shit that loons have been coming out with.
One thing I'm not sure about:
Not likely to be reasonable
"Visiting a vet’s surgery in person to renew a prescription (where this could be done over the phone)."
Reason: "visiting a vet’s surgery where a call would suffice would not be reasonable"
The legislation says
"to obtain basic necessities, including food and medical supplies for those in the same household (including any pets or animals in the household) including from any business listed in Part 3 of Schedule 2;"
and
"to seek medical assistance, including to access any of the services referred to in paragraph 37 or 38 of Schedule 2;"
The legislation says in respect of work
"to travel for the purposes of work or to provide voluntary or charitable services, where it is not reasonably possible for that person to work, or to provide those services, from the place where they are living;"
So we DO have a duty to work from home where possible. But that's the only case where we are REQUIRED to avoid doing something out of the home that could be done without leaving home. For example, if I can get food delivered from Amazon, I am not REQUIRED to get food delivered by Amazon and am at liberty to go the supermarket instead.
There doesn't therefore seem to be any grounds under which the police can argue that not renewing a prescription by phone is illegal.
Of course we should TRY to avoid the unnecessary trip, but that's not the point of this narrow discussion about whether it is ILLEGAL.
I would note that there have been people losing their shit about people, say, surfing. If you live close to the beach there doesn't seem to be anything remotely illegal about surfing.....
