No, it's not.
It's corruption. It's a branch of government claiming a power that does not belong to it.
If an issue did not exist in 1787, and it now needs to be addressed, the Congress needs to pass a law to address it. Lacking such a law, the courts have no basis on which to make such a ruling.
The courts do not have the legitimate authority to create new law, not even as “an inadvertent result of their ruling”.
