Does chronic pain automatically exclude coverage under the Medical Immigration Guidelines?

My reading of the cases cited by the applicant to support his assertion that chronicity alone takes a person out of the MIG is that the cases do not support his contention. Neither Arruda v Western, FSCO A13003926, 2015,[6] nor Lamasan v. Certas[7] suggest that chronic pain automatically excludes coverage by the MIG, and the cases are each distinguishable from this case. In Arruda the applicant’s position was uncontested, making the persuasive value of the decision weak. In Lamasan, the issue was compromised by the insurer having already paid for treatment beyond the MIG.
