For the issue to be addressed by the language rights support program or the future court challenges program, it would have to be argued that the bilingualism of justices sitting on the Supreme Court bench is part of having access to your preferred judge on the Supreme Court as part of your charter rights. Currently, the Supreme Court has an obligation to be bilingual as an institution. Nowhere is it said that justices themselves have to be bilingual. A case could be tried or could be brought forward. The panel of experts on the language rights support program would have to decide whether it is a worthy case. The cause is certainly worthy, but legally is it sound? Michel Francoeur would probably have an opinion on that. If you can tie it to a charter right, to a language right, you can be funded by the program.
