Until a new law is passed, the government and courts have a duty to follow the current law.

[kccqzy]

You have misunderstood what it means to follow the law. The law guarantees liberties, but doesn't guarantee prosecution. Obama has DACA, which gives young illegal immigrants a deferral on their prosecution. More generally there's the concept of prosecutorial discretion. Have you ever for example driven a car badly, been pulled over, but the cop let you off with just a warning?

[thfuran]

Or, for that matter, driven a car badly but not been pulled over at all? Surely in the interest of absolute lawfulness they then proceeded to the nearest police station to demand to be ticketed.

[remarkEon]

Surely you understand the difference between a cop declining to issue a speeding ticket and a federal "discretionary" policy that makes it de facto legal to violate standing immigration law at scale.
