It is the judgment of this Court that once an individual, having secured the office of the presidency by whatever means, including fraud, subterfuge, or concealment, has been duly sworn into said office, the legitimacy of their tenure is thereby affirmed. The Constitution, as interpreted herein, offers no mechanism for undoing the oath once administered, regardless of the integrity of the path taken to reach it.

Once sworn, always sworn. No take-backs.
