No. Answer is "No". If Healthcare minister says "lockdown" - nobody can say "No" - by law he may declare lockdown and even army must support his decision and by law is criminal not to support.
You don't understand: here is government of professionals. They have responsibility areas - each within own competences. Each of them is #1 in decisions within competences, and law warranties what professional decision will be implemented in life. The only way to stop - dismiss government or minister (Putin can dismiss minister, but can't appoint new one).
