Delay in filing statutory form triggers additional fee under Companies Act for late document submission. Where appointments meet Schedule XIII conditions, a return in Form No.25C must be filed within ninety days; belated filing of Form No.25C does not attract section 637B(b) but falls under section 611, and Registrars of Companies shall charge additional fee on belated Form No.25C filings at the rate standardized by Press Note No.2/95.
