הִטְעִים דְּבָרָיו לַדַּיָּן קֹדֶם שֶׁיָּבֹא בַּעַל דִּין חֲבֵרוֹ

ביטוי (אנגלית)

He emphasized his words to the judge before his opponent appeared

הגדרה (אנגלית)

He articulated or explained his arguments before the judge while the opposing litigant had not yet arrived. This is considered forbidden because the judge is susceptible to being persuaded by the arguments and liable to form in his heart a bias toward one side, thus losing objectivity.

(See above: Sotah 21b).
