Hold on, back up the bus. ‘Rules’ and ‘Ethics’ are very different things, and actually it’s ethics that inform rules, not the other way around. Ethics are the higher order here, but the same ethical principle could create quite different, even contradictory, rules.
Without falling down the Top-bar rabbit hole it’s a case that illustrates that difference. The ethical principle is merely that it is good to be able diagnose disease correctly and therefore hive construction that enables that is ‘good’. To regulate that good using Law we might therefore make a rule that combs have to be inspectable, but we might make a rule that frames have to be in a transparent tower, or that honey has to be sniffed, or whatever. To say that combs must be removable (whatever ‘removable’ means) is not an ethical principle. Rules are changeable, bound by circumstance, by expediency; ethics immutable. Rules have penalties, ethics don’t. Ethics are better thought of as a process used for reaching moral (‘correct’) decisions, not a decision itself.
If you want a set of rules head down the ‘Standard Operating Procedure’ track and revise it every year/month/day, but start with a set of coherent ethical principles.
