How could this have happened ? We forgot to point you to the EU Select Committee of the British House of Lords report on the Lisbon Treaty. It is entitled "The Treaty of Lisbon: An Impact Assessment". It was published back in March...Ouch.
That Committee is renowned for its high quality reports on EU affairs and this report is no exception.
It is probably the best, single publication to date on the new Treaty. Just go ahead and read it. But beware, the report itself is quite voluminous, about 300 pages long. The copious evidence provided by a wide range of individuals and organizations is available here.
