(a) It is clearly recognized that in the application of these procedures certain exceptional cases not clearly covered by the standards may arise. Any lot of seed may be rejected for certification if its quality in any respect not specifically covered by these standards is such that its value is not consistent with the purposes of seed certification.

(b) The certification agency can withhold the privilege of tree seed certification from any person or group of persons for cause, if it deems this action to be in the interest of maintaining the standards of seed certification.
