Thank you guys!
Here is my story, after my rejection I tried several times to contact CPC-Ottawa to review my case, I tried to convince them that my research assistant work experience letter clearly stated the lead statement as well as the related duties, but I never got any response. Then I tried the MP and asked him to send a letter to Ottawa and ask for a clarification on my application. In response, FA01772 came up with the same reasoning as the refusal email. In February, I suddenly ran into a case in the Federal court with the similar refusal reason ( listed duties that do not match the actions of the lead statement for research assistant work experience ), then I decided to pursue my case in the Federal court. During the preparation, I talked to 2 lawyers and both of them told me that I can not do anything in the court and it is better to reapply. They also said that even if I can quash the officer's decision, there is no guarantee that they granted me the PR visa, they can easily reject me again for another valid reason. But I decided to do this anyway and file a leave and Judicial review application in the Federal court. There are several steps involved in filing a judicial review application in the Federal court, one stage before the hearing, the justice department at the Immigration office decided to settle a deal with me outside the court. The problem with my application was the delay, if you want to file a judicial review application in the federal court, you have to do it within 2 weeks of the refusal decision. Otherwise, you have to file the application with extension of time and justify why you are late(which is really hard)
Generally this is a time consuming procedure if you want to do it by you own. If you decide to hire a lawyer, you have to spend 5000-10000$. You have to be very careful and only if you are 100% sure that the officer erred in law and make a wrong decision, you can think about the federal court. The best way to be sure is to find a similar case. Canadian legal system is common law, it means that the judges's decision are treated like a written law, so you can cite them in your case. All of the previous cases in the Federal Court are either on-line or you can order them at the Federal court's registry office in your town. Here are some useful links in case you need:
you can search some keywords in the previous decisions to find the similar cases. The whole process will take about 10-12 months and at the best, you can only quashed the officer's decision and return your application back to the visa office to review by another visa officer.
