"וְאַתָּה תֶחֱזֶה מִכָּל־הָעָם אַנְשֵׁי־חַיִל יִרְאֵי אֱלֹקים אַנְשֵׁי אֱמֶת שֹׂנְאֵי בָצַע וְשַׂמְתָּ עֲלֵהֶם שָׂרֵי אֲלָפִים שָׂרֵי מֵאוֹת שָׂרֵי חֲמִשִּׁים וְשָׂרֵי עֲשָׂרֹת׃ וְשָׁפְטוּ אֶת־הָעָם בְּכָל־עֵת וְהָיָה כָּל־הַדָּבָר הַגָּדֹל יָבִיאוּ אֵלֶיךָ וְכָל־הַדָּבָר הַקָּטֹן יִשְׁפְּטוּ־הֵם וְהָקֵל מֵעָלֶיךָ וְנָשְׂאוּ אִתָּךְ׃ "
"You shall also seek out from among all the people capable men who fear God, trustworthy men who spurn ill-gotten gain. Set these over them as chiefs of thousands, hundreds, fifties, and tens, and let them judge the people at all times. Have them bring every major dispute to you, but let them decide every minor dispute themselves. Make it easier for yourself by letting them share the burden with you. "
So besides Moses there were job titles "chiefs of thousands, hundreds, fifties, and tens". The advice continues dividing the disputes into "major" and "minor".
THe question is was there a hierarchy of those chiefs and subordination on to another (I don't know how it is called in English that one court is subordinated to a higher one), meaning that every dispute should be brought to the lesser court before it can be brought to a higher one? In a similar way to how Sanhedrins work.
