Statement u/s 161 cr.p.c.

My relative has filed an application u/s 482 Cr.P.C. in High Court challenging the summoning order of trial Court. She has used statements made u/s 161 Cr.P.C. to verify certain points which I'm sure is not permitted u/s 162 Cr.P.C. because it says such statements can be used by accused persons for contradiction and not for corroboration. Can this be done? Kindly suggest
