I think Shylock will have a fair trial because the duke is saying sorry to Antonio that the law is out of his hand’s.He calls Shylock a inhuman wretch,stony adversary,

•Inhuman wretch:

•stony adversary:saying he is a villain, cold hearted

•uncapable of pity:it showing he is dangerous and evil

The image we get from the judge is that he is a unfair man that will be ready to break the law to protect his friends like when he was talking bad about Shylock with Antonio.
