Limitation & repose for criminal law?

This is an academic question. A friend of mine insists that after 12 years, a criminal act is subject under Indian law to Repose (Limitation). I disagree. Who is right?

You are ..... limitation statutes as a matter of rule are not applicable on criminal statutes ..except (see 467-473 of the CrPC) as that would mean criminal only has to hide himself for a couple of years and then walk out with head held high. Crimes are never forgotten my dear. 

See the CHAPTER XXXVI of Cr. P. C. 'LIMITATION FOR TAKING COGNIZANCE OF CERTAIN OFFENCES' (Sections 467 to 473 of Cr. P. C.)

Thanks. That is what I thought, Besides, with DNA - cold cases are being reopened.
