Opposition members during the Joint Parliamentary Committee today termed as a "serious lapse" the non-submission of a Finance Ministry note on the 2G spectrum issue before the committee and demanded that the Finance Secretary be called before it to give clarifications.

As the JPC on the 2G issue met, CPI(M) member Sitaram Yechury raised the issue of the Finance Ministry note that suggested that the then finance
minister P Chidambaram could have insisted on auction of the radiowaves.

Yechury said the note in question was not among the documents submitted by the finance ministry to the JPC. He is understood to have contended that if the
non-submission of the 2G note was a deliberate act, it amounted to breach of privilege and if it was a lapse, it was a serious one.
