The attached letter dated 8th September has appeared on the PINS website with a publication date of 13th November and a description of "Representation accepted by the Examining Authority in to the examination".
Can you please explain why the Examining Authority is accepting submissions:
1. from persons who have not registered an interest;
2. at a point in the examination when other interested parties cannot respond effectively to them?
What does "accepted in to the examination" mean please?
The letter refers to a 62 page report which, as far as I can tell, has not previously been mentioned during the examination. Are we to assume that the report is also "accepted in to the examination"? If so, how are we expected to absorb and respond to such material at this stage? We respectfully submit that, unless the report has been properly introduced at an earlier stage, it should be disregarded by the ExA. It is not "independent" as claimed in the letter - a disclaimer on page 4 says "This study has been commissioned by Tidal Lagoon Power Ltd (TLP) ..."

Further to your query, there is provision under the Planning Act 2008 for the Examining Authority to accept written representations by parties other than interested parties under the Infrastructure Planning (Examination Procedure) Rules 2010, Rule 10(3) in to the examination.
There is an opportunity for all parties to comment on this submission at the next deadline.
As noted in your comment, the report is referenced in the representation but is not before the Examining Authority or interested parties. Should you have comments on this representation, the opportunity to put these to the Examining Authority will be by 25 November 2014.
I hope that this information is of assistance.
