Rule 211 was proposed on 00000000000000 by .

If two or more mutable rules conflict with one another, or if two or more immutable rules conflict with one another, then the rule with the lowest ordinal number takes precedence. If at least one of the rules in conflict explicitly says of itself that it defers to another rule (or type of rule) or takes precedence over another rule (or type of rule), then such provisions shall supersede the numerical method for determining precedence. If two or more rules claim to take precedence over one another or to defer to one another, then the numerical method again governs.
