Looked a joint over (5)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">looked a joint over</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for cased that I've seen before include "put in a box" , "examined with intention to rob" , "Covered, protected; checked over (by robber)" , "Reconnoitred (sl.)" , "Carefully inspected (for crime)" .)
