1. Order IX of the Code of Civil Procedure deals with the appearance and non-appearance of parties before a court.
2. If both parties fail to appear, the suit can be dismissed. Dismissal does not amount to a decree and no appeal lies, but the plaintiff can file a fresh suit or apply to set aside the dismissal.
3. If the defendant fails to appear after being duly served, the case can proceed ex parte, but the defendant can apply to set aside the ex parte order by showing sufficient cause for their non-appearance.
