What are some examples of unjust?

According to Jesus Christ / Yeshua Ha Mashyiach, those laws that take the substance owned by widows and orphans are unjust. Any law that is an unjust burden to the bearer is unjust. Any laws that are not based in the Word of God are unjust. All just laws are supported by scriptural principle.

Criminal case witnesses in The Bible had to have at least two witnesses that agreed in their testimony to convict a person of an offense. This was just because if the witnesses were found to be false witnesses, to lie, they would receive the same punishment as would have been executed upon the accused if he had actually done the offense.

Therefore the laws on perjury lack much in justice.
