Apparently, they're "in the post".
ACS Law: "“The first batch [of] claims have been prepared and were filed at court on Friday, 4 September 2009. Service of the proceedings will be made by first class post and will be with defendants by Tuesday, 8 September 2009 at the very latest,” the company said in a statement, adding, “The second batch of defendants will be selected on Monday, 14 September 2009.”"
