The Registration System has been implemented for several years. On
the one hand, it has solved the problem of ‘difficult to prosecute’, on the other
hand, it leaves corresponding problems in practice. In the current context, the
review of ‘legitimate parties’ is in the gray area between ‘formal review’ in the
case filing stage and ‘substantive trial’ in the trial stage. Once the situation of
improper parties has been found during the defense period, it is inevitable to
delay the procedure. By investigating the relevant litigation systems abroad and
combined with the current situation of judicial practice in China, the author
believes that it is necessary to build a pre litigation preparation procedure
suitable for current situation around the Registration System, so as to ensure
the smooth progress of the procedure and avoid repeated procedures and tired
tripartite litigation.
