Descend via STAR, after getting crossing restriction previously

Question

The ATC issues "Cross BHAWK at FL240" initially. After few minutes, the ATC instructs "Descend Via FYTTE5 arrival". Should we comply with the crossing restriction at BHAWK, or the restriction can be omitted?

The JO 7110.65Y says

Clearance to “descent via” authorizes pilots:

1. To descend at pilot discretion to meet published restrictions on a STAR.

and

“Climb via SID except after Baret, maintain flight level one niner zero.”

NOTE1. Considering the principle that the last ATC clearance issued has precedence over the previous, the phraseology “maintain (altitude)” alone cancels previously issued altitude restrictions, including SID/STAR altitude restrictions unless they are restated or modified, and authorizes an unrestricted climb or descent. Speed restrictions remain in effect unless the controller explicitly cancels the speed restrictions.

However, the example given in "descend via" does not say anything about "previous assigned crossing altitude." And the note given in "climb via" example only explains the phraseology "maintain" would cancel previously issued altitude.

Is there any FAA document stating the altitude restrictions assigned previously can be omitted or still valid, after getting "descend via" clearance?

Answer 1

The restriction to cross "BHAWK at FL240" is overridden by the controllers latest clearance to "Descend Via FYTTE5 arrival", unless they include the instruction descend via "EXCEPT MAINTAIN FL240".

If unsure, you should query ATC though.

Answer 2

In JO 7110.65, 4−2−5. ROUTE OR ALTITUDE AMENDMENTS. b. When route or altitude in a previously issued clearance is amended, restate all applicable altitude restrictions.

The example given:

“Amend altitude. Cross Ollis intersection at or above Three Thousand; cross Gordonsville V−O−R at or above One Two Thousand; maintain Flight Level Two Four Zero.”

(Shortly after departure, altitude restrictions are no longer applicable, the controller issues an amended clearance as follows):

“Climb and maintain Flight Level Two Four Zero.”

When issuing an amended altitude (cross BHAWK at FL240 >>> Descend via STAR to bottom altitude), ATC should restate all altitude restrictions if applicable. If not restated, it's no longer needed.
