Explanation:

Fugitive Slave Act of 1850 also known as Compromise of 1850 was the act that denied the slaves from the right of a jury trial. This law also enabled individuals to forcibly capture runaway slaves. Penalty was imposed on them with the punishment of six months in jail if they try to interfere with the laws.
