In light of the next year's expansion draft and the ruling that players with NMCs must be protected within said draft, Anaheim's GM Bob Murray is rumored to be "working to change Kevin Bieksa's no-move clause." His two-year contract extension kicks in on July 1st and with it, the NMC. Not knowing that a GM could renegotiate the terms of a previously agreed upon contract so long as it hasn't begun, I decided to do some digging within the CBA...
Assuming I have not missed any relevant articles within the CBA, is it fair to say Bob Murray may--pending the approval of Bieksa and his agent--renegotiate the contract extension to omit the NMC?
The clause you quoted does not support that it can be renegotiated.
11.10 No Renegotiation. In no event shall a Club and a Player negotiate a change in any terms
of a Player's SPC for the then-current season or for any remaining season of an SPC (except as
provided for in Section 11.8(b)). This provision shall not prohibit a Player and Club from
negotiating an extension to an existing SPC in accordance with the terms of Section 50.5(f)
hereof, or from negotiating a new or reformed SPC or Offer Sheet in the limited context
and time-frame expressly set forth in Section 11.6(a)(vi) above.
The first underlined section says team/player can negotiate an extension. Well, that already happened with Bieksa. The extension (which is actually just a completely new SPC) has already been signed and registered with the NHL.
The second underlined section says team/player can "negotiate a new or reformed SPC" in the limited context of Section 11.6(a)(vi). Section 11.6(a)(vi) covers the situation where the NHL rejects an SPC. That rejection could be due to something wrong with the SPC terms, or it could be that the SPC terms themselves would be fine, however the SPC would put the team over the salary cap or cause some other prohibited roster state. In other words if the NHL rejected the SPC then the team/player can submit a new SPC with different term. This section would not apply to Bieksa as his SPC was not rejected.
Section 11.8(b) applies to having an NMC in a new extension be retroactive to existing contract. In other words, this section says the existing contract can be modified to add an NMC/NTC as a result of the player signing an extension with an NMC/NTC. The clause does not allow for the extension SPC's NMC or NTC to be changed. So, again would not apply to Bieksa.
I'm sure Murray could ask Bieksa if he's willing to waive his NMC or make his NMC decisions on some criteria other then what's in the contract. However they cannot rewrite the contract term or make any binding agreements outside of the contract how the NMC will be applied.
