British law, grammar and discrimination

On Brighton & Hove Issues Forum, Ed Bassford wrote this recently :

 "It's not down to the drafters of legislation to be creative. They comply
 with Section 6 of the Interpretation Act 1978:-
 
 6. Gender and number.
 
 In any Act, unless the contrary intention appears,-
 (a)words importing the masculine gender include the feminine;
 (b)words importing the feminine gender include the masculine;
 (c)words in the singular include the plural and words in the 
 plural include
 the singular.
 
 There are two specific pieces of law that disapply this 
 provision:-
 The Sexual Offences Act 1985 and the Employment Act 1989."
