Although I wasn't directly involved with the Murphy case I did receive a complete transcription of the trial and have both studied it closely and shared it with a few select others.
What I have posted previously is, to the absolute best of my knowledge and interpretation, the technical reality.
It is simple as can be.
Dave Murphy was charged, went to court and was found to be "Not guilty" and exempted from the HP restriction.
Nobody else has. The ruling was specific and clear in that Dave and only Dave was exempt.
No other guide, rather they work for Dave or not, has the same exemption as Dave does.
As I noted, it's a "strange duck" and unique as far as I can tell.
Restrictions on other bodies of water are not really relevant to this case, being unique and all that.
I try to be clear in what I post so there it is.
Take care.
