There are times, albeit rarely, when the US can remind us of the importance of the need for precision in written communication.  This is particularly the case where documents that may be scrutinised in a Court of Law are concerned.  The omission of an ‘Oxford comma’ which, had it been inserted before the word ‘or’, would have defined ‘distribution’ as a discrete activity from ‘packaging’ related activities may have cost a Maine employer millions of dollars in overtime back-pay.  In the UK, lawyers have striven to make the comma an endangered species: I wonder how may are now checking their long-established precedents to see whether, in the light of this case, they should be re-introduced.
