Whether the appeal against the order refusing admission of new allegations and evidence was admissible under Art. 319 lit. b CPC.
The refusal to admit novas can be challenged only if it is capable of causing difficult-to-repair harm; that condition was not met here.
Any errors about the date of knowledge of the new facts or compliance with Art. 229 CPC can be raised in an appeal against the final judgment. The appellant therefore retains an adequate remedy in the main proceedings, so no irreparable disadvantage exists.
