What impact does incorrect revocation information of a certification authority certificate have on the certification authority?

The following describes the effects on certification authority operation if the revocation information for one of the certification authority's certificates cannot be retrieved.

This case may also occur as planned, for example, when a previous certification authority hierarchy is to be decommissioned.
