Why describes mostly every law enacted by a parliament? They clearly have that power to change the laws they enacted at any time.
So where is the problem if parliament delegates this power to some executive entity?
Now, if delegation is not clearly defined, this is another issue I can understand. And I am not interested enough in the minutia of US legislation to have an opinion on that.
They don't have the power to reinterpret their laws. They can repeal laws and pass new laws, but interpretation is up to the courts, if they don't like the interpretation the court gives to a law then their recourse is to pass a new law.

The problem is firstly that the executive isn't supposed to have the power to make or repeal laws, "delegating" it to them breaks the separation of powers, and secondly allowing a law to be "reinterpreted" rather than rewritten breaks the whole system of precedence that the rule of law depends on.
