You can find a new "Verify" button when editing rules. This button makes use of drools-verifier, which may be used to perform what you are trying to do. We are working hard these days to add field and fact restrictions to guvnor.

I am also interested in having business logic validation capabilities in
Guvnor. Ideally our users would like to be prevented from creating new rules
that conflict with existing rules or changing existing rules in a way that
produces conflict with other existing rules.

Do you know of any way of notifying Guvnor users that a rule they want to
create or have created is in conflict with existing ones?
