No, all laws passed by the legislature need to be sunset. 20 year max for safety stuff, 10 for all others, and should be set at time of legislation debate.

Constitutional amendments would not expire, but should be able to be changed, added, deleted by super majority in both the legislature and general vote. 66 to 75%

If a law is so important to the general populace, it could become permanent through a constitutional change vote.

This should also apply to the US laws, but without a general populace vote. Permanent laws requiring a super majority to pass, change, delete, along with presidential signature.
