I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">seek retribution in a way</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 sue that I've seen before include "Prosecute at law" , "Apply" , "Litigious girl" , "Start proceedings against (someone)" , "Susan (dim.)" .)
