Obiter reported a few months back on the dangers of fingers slipping on keyboards, with our chief typo correspondent David Wershof of Wiseman Lee informing us of an unfortunate client who confused ‘possible’ with pissible’ on his BlackBerry, with tragic consequences. Now the vigilant Wershof has noticed that it is not just the proximity of ‘o’ and ‘I’ on the keyboard that causes trouble; next-door neighbours ‘r’ and ‘t’ know how to wreak some havoc as well. See if you can spot what happened in this interpretation clause sent to Wershof by a big commercial firm: ‘The obligations of or restrictions on the tenant… are without prejudice to the obligations of… the guarantor or to the tights of the landlord under any other clause.’ The tights of the landlord? Obiter wonders whether this particular lease was for anywhere near Sherwood forest. Keep it coming, Wershof.
