Page "Roman law" Paragraph 13

Thus, over the course of time, parallel to the civil law and supplementing and correcting it, a new body of praetoric law emerged.

In fact, praetoric law was so defined by the famous Roman jurist Papinian ( Amilius Papinianus — died in 212 AD ): " Ius praetorium est quod praetores introduxerunt adiuvandi vel supplendi vel corrigendi iuris civilis gratia propter utilitatem publicam " (" praetoric law is that law introduced by praetors to supplement or correct civil law for public benefit ").

Ultimately, civil law and praetoric law were fused in the Corpus Juris Civilis.
