Ni sheria ipi itumike Kwenye hili.... ?

Is it right to use Section35(3) of the Education Act of tz on the offence of impregnating a school girl?
While there is an amendment on 20/May/2016 under Section 60A of the Education Act.
Hii Nimeiona Kwenye charge sheet Ambayo imefiliwa 2017 Lakini kosa limetokea 2015.....je ni sawa kutumia sheria ya zamani Kwenye hili?
Explanation plz..

Sheria inaweza act RETROSPECTIVE??
