“TLL knew of the summons which led to the liability order. The liability order was referred to in evidence that was filed in April 2008. The liability order was specifically referred to in a letter dated10 November 2009 (which even on its own case TLL accepts it received on15th November 2009 ): and yet no application was made to the council until February 2010 to set aside the order. That seems to me clearly not the degree of promptness that is required if this exceptional jurisdiction is to be exercised.”
