The plea comes over nearly two months after the MCA asked the tribunal to ban both the firms from audit operations in the country for a period of five years.
According to the Serious Fraud Investigation Office (SFIO), Deloitte had disregarded the Reserve Bank of India's (RBI) regulations and turned a blind eye to IFIN's "evergreening" of loans, and never cross-checked any of the certificates the company used to mislead lenders.
Both Deloitte and the KMPG arm BSR & Associates, the investigation showed, had failed to fulfill their duties as auditors.
In June, BSR & Associates resigned as the statutory auditor of the financial arm of IL&FS after the MCA sought a ban, while Deloitte was the statutory auditor of IFIN till the financial year 2017-18.
The NCLT has already reserved its order on the plea to ban both the firms.
The crisis in the infrastructure lending major IL&FS came to light in September last year when it defaulted on its commercial papers, a short-term debt instrument. Following the crisis, the government appointed a new board led by Uday Kotak.
Investigations into the matter have opened a can of worms with both the auditors and the rating agencies of IL&FS and its group companies along with the erstwhile management under the scanner. Few of the prevous IL&FS top officials have also been arrested in this connection.
