Looking at the unfair contract regulations.  Schedule 2 (1) (n) of The
Regulations says a term which may be regarded as unfair, has the
object or effect of  limiting the seller's or supplier's obligation to
respect commitments undertaken by his agents or making his commitments
subject to compliance with a "particular formality";

Was wondering exactly what this means?  "Particular" can mean all
sorts of things, was wondering if it is a standard legal phrase with a
standard meaning.
