'unjustly-conducted' originates from the combination of 'unjustly' and 'conducted'. 'Unjustly' comes from 'unjust', which originates from Latin 'iniustus', where 'in-' meant 'not' and 'iustus' meant 'just'. 'Conducted' comes from Latin 'conductus', where 'con-' meant 'together' and 'ducere' meant 'to lead'.

'Unjustly' evolved from Middle English 'unjust', and 'conducted' evolved from Middle English 'conducten'.

Initially, 'unjustly' meant 'not just', and 'conducted' meant 'led or managed'. Together, they evolved to mean 'performed in an unfair manner'.
