No.    The investigation of the accused did (as a function of Benedict's initiative) fall under the CDF, but this matter is related to the care of the abused not an investigation and adjudication of the accused.   

Care for the soul falls under the local bishop, and thus under the Congregation for Bishops, as the article points out.

We must resist the temptation to lump all matters and all related matters under the CDF.  

Subsidiarity.
