Unless you invoke Rule 9 and see those notes from the court or GCMS where it is explicitly mentioned that the File was processed by Chinook, there is no way to ascertain that it was refused by Chinook.
Furthermore, in order for you successfully turn around the refusal , you need to be able to establish that your original application satisfied all the pre-requisites for the visa
Simply put, when you do a JR, they do not automatically approve your visa. The file is sent to a diff Visa Officer for re-determination & during the process, you may be asked to provide Additional Docs too. Outcomes are not certain and it can take 3-6 months or even longer depending on complexity of the file
If I were you, I will apply for the case notes [GCMS] and start from there and may be set up a consult with an attorney to understand my options.
Good Luck
