Mick O'Dwyer stepped down as Clare manager after powerful periods immediately before and after half-time was enough to see Laois past his Clare side, 3-17 to 0-10, in round two of the qualifiers in Cusack Park, Ennis.
O'Dwyer's has decided not to seek a second year in charge of the Banner men on the back of this defeat.
Goals either side of the break from John O'Loughlin and David Conway set Laois on their way to victory, but they cut lose in the second-half, allowing Clare just four points in a stingy defensive display.
Ten minutes before half-time Clare had led by four points after a strong opening period, but they failed to hit the target for the next 27 minutes until David Tubridy landed his fourth point.
But by that stage Laois had the win secured and led by 2-12 to 0-07 after their forwards finally found the target after hitting ten wides in the first-half.
Initially Clare made plenty of progress by feeding direct ball into Ger Brennan, who once again braved a broken rib to line out for the Banner.
He was involved in everything good that Clare did early on and, after his move to the edge of the square, the points began to flow for Clare.
Darren Strong had given Laois the lead in the second minute, but Clare hit back with three in a row from David Tubridy (2) and a great score from Rory Donnelly in the ninth minute.
Laois looked in slight disarray at this juncture, especially when Tubridy and Donnelly found the target again to open their lead out to 0-05 to 0-02.
It could have got a lot worse for the O'Moore men in the 25th minute when wing-back Graham Kelly charged down on goal, only for his blistering drive to clear the crossbar.
But that's where Clare's positive day ended and Laois went on to hit 1-05 before and after half-time to end the contest.
The key score arrive in the 31st minute when O'Loughlin finished smartly to the net after Donie Kingston's clever pass over the top, but five minutes after the restart David Conway found the top corner for a splendid goal to end any Clare hopes.
David Tubridy kept Clare's score respectable with three second-half frees but, late on, Munnelly palmed to the net form close range to crown the Laois win.
