[cabfpub] Pre-Ballot 209 EV Liability

Thu Oct 12 18:27:16 UTC 2017

Moudrick and others,

Is the following proposed change to section 18 of the EV Guidelines more clear?

18.  Liability and Indemnification

CAs MAY limit their liability as described in Section 9.8 of the Baseline Requirements except that a CA MAY NOT limit its liability to Subscribers or Relying Parties for legally recognized and provable claims to a monetary amount less than one or any combination of the following: 

(1)    two thousand US dollars ($2,000) - per Subscriber or Relying Party per EV Certificate;

(2)    one hundred thousand US dollars ($100,000) – aggregated across all claims, Subscribers, and Relying Parties – per EV Certificate; or

(3)    five million US dollars ($5,000,000) – aggregated across all claims, Subscribers, and Relying Parties – for all EV Certificates issued by the CA during any continuous 12-month period. 

Thanks,

Ben

Thanks, Ben.

Assuming that any combination (of 1,2, 3) or no combination at all would be acceptable, could we add something like "at least one or any combination of following" so that it is explicitly clear?

Thanks,
M.D.

CAs MAY limit their liability as described in Section 9.8 of the Baseline Requirements except that a CA MAY NOT limit its liability to Subscribers or Relying Parties for legally recognized and provable claims to a monetary amount less than:

Rather than tack on these two additional limits, what if it were simplified to read:

CAs MAY limit their liability as described in Section 9.8 of the Baseline Requirements except that a CA MAY NOT limit its liability to Subscribers or Relying Parties for legally recognized and provable claims to a monetary amount less than: 

                 (1)  two thousand US dollars per Subscriber or Relying Party per EV Certificate;

                 (2)  one hundred thousand US dollars – aggregated across all claims, Subscribers, and Relying Parties – per EV Certificate; and/or

                 (3)  five million US dollars – aggregated across all claims, Subscribers, and Relying Parties – for all EV Certificates issued by the CA during any continuous 12-month period. 

These limitations are notwithstanding anything in the Baseline Requirements purportedly to the contrary.

A CA's indemnification obligations and a Root CA’s obligations with respect to subordinate CAs are set forth in Section 9.9 of the Baseline Requirements.

Would this work?

Notwithstanding the foregoing, a CA MAY limit its liability to Subscribers or Relying Parties for legally recognized and provable claims to not less than: (1) one hundred thousand US dollars – aggregated across all claims, Subscribers, and Relying Parties – per EV Certificate; and/or (2) five million US dollars – aggregated across all claims, Subscribers, and Relying Parties – for all EV Certificates issued by the CA during any continuous 12-month period.

Would you mind to show how it would sound now? :)

Never mind – I think I now see your point.  Not “up to” it needs to be “not less than $5 million.”  Would that make it clearer?

It’s permissive – a CA MAY limit its liability.   Maybe we should say “up to $5 million”.   Then, would that be clearer -  that it can be less than $5 million?

With "and" I don't see its optional.

Again, just to understand the model: is per EV certificate amount is NOT fixed whereas 12-month continuous amount is the only option ($5 mln.)?

Thanks,
M.D.

All of the provisions would provide optional caps that CAs could place on EV liability.  The 12-month $5 Million cap allows a CA to cap all EV liability to all those EV certificates issued within a single year.

Ok. Do I understand the intention correctly: to have a "floating liability" amount per EV certificate and "fixed liability" amount per continuous 12-month period?

Thanks,
M.D.

No. Because they MAY do both.  An “or” would mean that they have to choose between the two, which isn’t the intent.

Hi Ben,

could it be "or" between (1) and (2)?

Thanks,
M.D.

Here is another pre-ballot for discussion.

Ballot 209 - EV Liability

In Section 18 of the EV Guidelines, add the following sentences to the end of the first paragraph:

Notwithstanding the foregoing, a CA MAY limit its liability to Subscribers or Relying Parties for legally recognized and provable claims to: (1) one hundred thousand US dollars – aggregated across all claims, Subscribers, and Relying Parties – per EV Certificate; and (2) five million US dollars – aggregated across all claims, Subscribers, and Relying Parties – for all EV Certificates issued by the CA during any continuous 12-month period. These limitations are notwithstanding anything in the Baseline Requirements purportedly to the contrary.

Such that Section 18 of the EV Guidelines would read:

CAs MAY limit their liability as described in Section 9.8 of the Baseline Requirements except that a CA MAY NOT limit its liability to Subscribers or Relying Parties for legally recognized and provable claims to a monetary amount less than two thousand US dollars per Subscriber or Relying Party per EV Certificate. Notwithstanding the foregoing, a CA MAY limit its liability to Subscribers or Relying Parties for legally recognized and provable claims to: (1) one hundred thousand US dollars – aggregated across all claims, Subscribers, and Relying Parties – per EV Certificate; and (2) five million US dollars – aggregated across all claims, Subscribers, and Relying Parties – for all EV Certificates issued by the CA during any continuous 12-month period. These limitations are notwithstanding anything in the Baseline Requirements purportedly to the contrary.

A CA's indemnification obligations and a Root CA’s obligations with respect to subordinate CAs are set forth in Section 9.9 of the Baseline Requirements.
