This law proposal was not actually proposed in the Knesset, yet, but it is interesting. This proposal comes from the Council of Torah Sages of Agudas Yisrael and they encourage the Haredi Members of Knesset to pass this in Knesset.

The issue of Shabbos, and other religion-State issues, is all dependent on what is called the "status quo agreement". This was a communal agreement between David Ben Gurion and Agudat Yisrael regarding how to deal with religious issues in a secular State. This never had a real legal standing, and it is amazing that for the past 70 or so years it has actually held up and continues to direct the sensitive decisions in matters of religion and State.

The Moetzes has decided that it is time to move beyond the letter and turn it into actual law. They want the Haredi MKs to pass the various points in the status quo agreement into actual law.

on the one hand, the status quo agreement is unofficial and fairly flimsy, and any government can decide to not follow it any longer, so turning it into law solidifies it.

on the other hand, turning it into a law means any other government can overturn the law, the way each government overturns other laws passed by previous governments. So turning it into law puts it into actual risk of one day being rejected. But then again, not as a law it is also at risk of being rejected. But as a law it can be officially rejected.

Anyways, as until now the Status Quo has pretty much reigned supreme, I do not see it being too difficult to pass if the MKs decide to try and pass it.
