PLease know that frustration coming out from Judge decissions is everyday´s bread in the life of a lawyer. Nothing surprising.
Also, take in mind that Judges apply law according to the evidences and the defense brought to them, that is the reason why a decission on very similar issues ( never the same) can be so different: different person judging, different evidences brought, different defense acted.
It happens in every country.
Justice does not finish in first instance courts.
