ἀνεπικρίτως
From LSJ
ὃν οὐ τύπτει λόγος οὐδὲ ῥάβδος → if words don't get through, neither a beating will | if the carrot doesn't work, the stick will not work either | whom words do not strike, neither does the rod
Russian (Dvoretsky)
ἀνεπικρίτως: без решения: ἀ. διαφωνούμενος Sext. служащий предметом бесконечных разногласий.
