Rambam - Sefer HaMitzvos: Negative Mitzvah 322: Negative Mitzvah 322

This is not an error of duplication. The full-fledged version of this Mitzvah are many and change for those who are learning the one/three chapter a day. The Message for the day from "Bringing Heaven Down to Earth" at the end of this Mitzvah is different than that of yesterday.

Negative Mitzvah 322: It is forbidden to administer death penalties on Shabbat
Exodus 35:3 "You shall kindle no fire throughout your settlements on the Sabbath day"

The Beit Din has the authority to punish and even execute, criminals, however, it may not administer the death penalty on Shabbat.

The philosophers are only trying to be nice to G-d: They can't allow an Infinite Being to get His Complete Simple Unity messed up with a lowly, material, fragmented world. And so they banish Him to the far, ethereal heavens, as removed as possible from our world. By their way of thinking, you can forget about miracles, prophecy or divine intervention in your life. G-d is just too far out there. Those philosophers are fools. In their groping for the infinite, they have ended up with a G-d bound by the limitations of the human mind. In fact, the ultimate measure of the Infinite is that it can be found within the finite as well. G-d is here now, within every thing, and G-d is One.
