U radu autor najpre ukazuje na osnovna obeležja nezavisnosti sudstva kao načela koje je od ključne važnosti za ostvarivanje vladavine prava. On naročito insistira teorijskom razlikovanju de iure i facto nezavisnosti. Potom analizira ustavne zakonske propise, dajući kratak osvrt istoriju sadašnjost pravosuđa, zaključujući da jaz između pravne faktičke, odnosno suštinske u Srbiji još uvek prilično veliki, bi trebalo strateški osmisliti reformu Ustava delu o pravosuđu, što do danas očigledno...
