I explained the context of the current controversy last year (here):
In 2012, the American Law Institute (in which I am a member), agreed to launch a revision of its famous and quite influential Model Penal Code to focus specifically on rising issues of "sexual assault and related offenses." The project It was acknowledged at the time that the issue of the decriminalization of certain conduct around sexual activity "deals with some of the most controversial matters on the current public agenda." (Richard L. Revesz, Director ALI in Forward ALI Model Penal Code: Sexual Assault and Related Offenses (Tent. Draft No. 2 (April 15, 20916). The project has been overseen by its reporter, Stephen J. Schulhofer and its associate reporter, Erin E. Murphy, both of NYU Law School. But it has been highly controversial as I reported in 2014 (see, Sexual Assualt at the American Law Institute--Controversy Over the Criminalization of Sexual Contact in the Proposed Revision of the Model Penal Code).
The controversy is well evidenced by the history of this project before the ALI. In 2013, a draft on procedural and evidentiary principles applicable to the sexual assault provisions (¶ 213 of the Model Penal Code) and on collateral consequences of conviction was presented to ALI for discussion but no vote. For the 2014 ALI meeting, a tentative draft containing substantive material for discussion and an evidentiary section (proposed revision ¶ 213.7) for approval was submitted but no vote was taken. Again, for the 2015 meeting a draft on substantive and evidentiary material was presented for discussion but no vote. For its 2016 meeting, the ALI is asked to consider for approval two key provisions: ¶ 213.0(3) (definition of consent) and ¶ 213.2 (sexual penetration without consent).
