A report on Kan 11 has revealed that the rabbinic council of the Chief Rabbinate of Israel met back in November 2019 and reaffirmed the Beta Israel community of Ethiopians as full Jews, as per the psak of Rav Ovadia Yosef some 47 years ago.

I do not know why they needed to reaffirm the psak now, nor is it known why this meeting and reaffirmation was kept secret until now, but it happened.

Whatever the reason, I would expect the Rabbanut to enforce the decision in whatever way is relevant, treating them as full Jews and fighting racism against this sector.
