With 19:26 we begin another section in the Proverbs, and it continues through 22:16. The theme of this section is acknowledging God in everyday life. Ironically, it starts with the last four verses of Chapter 19, which are about mocking; the first verses about mocking in the family, and the second 2 are mocking in court.

Whoever robs their father and drives out their mother
    is a child who brings shame and disgrace.

Stop listening to instruction, my son,
    and you will stray from the words of knowledge.

Proverbs 19:26-27

Verse 26 speaks of a child who does not make any provision for his parents in their old age. The father is left with nothing, and the mother is forced from her home and must seek help from others. Verse 27 speaks to a son with a warning that if he does not listen to wise teaching when he is young, or if he sits there and listens with no intention of following those wise teachings, that he is headed for ruin in this life.  Nothing much has changed since this was written, has it?

A corrupt witness mocks at justice,
    and the mouth of the wicked gulps down evil.

Penalties are prepared for mockers,
    and beatings for the backs of fools.

Proverbs 19:28-29

A corrupt witness is an evildoer. He gulps down evil, which is to say that he fills himself with evil instead of taking in wisdom. By his testimony, he mocks justice, and I might add that in mocking justice, which comes from God, he also mocks God.

Finally, verse 29, at least by implication, cuts right to the bottom line of this passage: Mockers are fools. Those corrupt individuals who give false testimony will face punishment. Their punishment will come in this life if they are caught, and most certainly when God judges everyone.
