Mosiah 29:26 - 29:30

Mosiah 29:26 Now it is not common that the voice of the people desireth anything contrary to that which is right; but it is common for the lesser part of the people to desire that which is not right; therefore this shall ye observe and make it your law—to do your business by the voice of the people.

Now since most of the time the people as a whole desire good things and a small part of the people desire evil things, let the business of the people be done by common consent.

Mosiah 29:27 And if the time comes that the voice of the people doth choose iniquity, then is the time that the judgments of God will come upon you; yea, then is the time he will visit you with great destruction even as he has hitherto visited this land.

However when the majority of the people choose wrongly, their destruction is not far off. And it will be the Lord that brings it upon a wicked people just as He did on the people of king Noah.
[The question: is this system of government a pure democracy? It sounds like it me. It seems to be that the people vote on new laws or public projects rather than by representatives of the people as in a republic. And lawbreakers are brought before the judges for judgment for crimes committed against the people.

Mosiah 29:28 And now if ye have judges, and they do not judge you according to the law which has been given, ye can cause that they may be judged of a higher judge.

Mosiah also proposes a check and balance system for the judges. If a lower judge fails to judge according to the laws on the books, say lets a thief off when it is clear that the person is guilty and some think a bride was given, then the people can take this judge before a higher judge.

Mosiah 29:29 If your higher judges do not judge righteous judgments, ye shall cause that a small number of your lower judges should be gathered together, and they shall judge your higher judges, according to the voice of the people.

If it should be that a higher judge does not do right in his office, he can be called up before a group of lower judges. This will be again because the people have brought this higher judge to judgment.
[It sounds like it has to be the people who bring judges for judgment not the judges themselves. I’m guessing that this makes it so that the judges cannot get together to put in their own men and get rid of the ones that will not go along with any particular agenda. This would go along with Mosiah’s contention of letting the people be in control of the government.]

Mosiah 29:30 And I command you to do these things in the fear of the Lord; and I command you to do these things, and that ye have no king; that if these people commit sins and iniquities they shall be answered upon their own heads.

Mosiah states that with this system, the sins of the people will be upon their own heads. No one will be to blame for the condition of the people. It will be their own fault if the people are wicked.
