As a CSCC Officer I'll reply.
The text of the email was:
Dear BCA Member,
BCA is currently conducting a poll of its members as to whether to
campaign for CRoW applying to caves or not. The poll will include your
members.
BCA have not included any campaigning information with the ballot papers
upon which your members can make an informed decision.
The CSCC would be grateful if you could distribute the attached document
to your members which puts the case for a NO vote. No doubt you will
receive a similar request from the pro camp before long.
Regards
Frank Tully
CSCC Secretary.
A copy of the attached document referred to is at

The Secretary was doing as he was mandated to do by the previous CSCC meeting which was to distribute the CSCC's view to the BCA member Clubs so that they could pass it on to their members.
We are in the middle of a campaign and CSCC are campaigning. This is no different to the post you receive from the political parties around election times.
The mailing list was constructed from CSCC's own members and the email addresses publicly available on the Club's own website.
That email list should not have been broadcast to all recipients. It was a genuine mistake caused by not understanding the difference between CC and BCC.
On behalf of CSCC I wish to offer an unreserved apology to those effected. It should not have happened and we will do our best to make sure it doesn't happen again.
