Lots of WTO Disputes This Year

Here is a table showing WTO complaints (consultations requests) for 2004-2012:

YearNumber of Standard DSU
Complaints, by year
2012 14
2011 8
2010 17
2009 14
2008 19
2007 13
2006 20
2005 12
2004 19

Here's a similar table for "matters", which is a subjective judgement we (i.e., WorldTradeLaw.net) made to group certain similar cases together:

YearNumber of Standard DSU
Matters, by year
2012 10
2011 7
2010 12
2009 9
2008 13
2007 7
2006 17
2005 10
2004 18

What jumps out at me is that the figures for the first (approximately) 7 months of 2012 are equal to or greater than several prevous full years.  We are on pace for about 24 complaints this year.

What's going on?  Why the increase?   I'm not sure, but let's look at the list of 2012 complaints to see what's in there:

Nothing in particular strikes me as significant here.  Just the usual mix of cases, but more of them.  So is this a trend?  Or just an aberration?
