UK Borders Bill

My Lords, I have a drafting point on Clause 2. On page 1, line 14, there is the word ““thinks””. I can be quite brief, as we have had this many times before, in this Bill and in other legislation. ““Thinks”” is too vague. It would be much better to have ““is satisfied””, particularly in view of the serious consequences that can flow from an immigration officer using these powers.
