derogation

An act which belittles; disparagement.

Always have the greatest excesses and the most reprehensible practices been committed when backed up by or given the sanction of religion. But all this represents no derogation of the original phallic cult per se. It merely proves that the gods have always been what we have made them.

The act of derogating; the temporary or partial nullification of a law.

Two sets of Mk. 2 coaches hauled by Class 37s were introduced on peak Rhymney services during the summer. The coaches do not comply with the Persons with Reduced Mobility (PRM) standards and would therefore need a derogation to continue in passenger service after 31 December.
