Someone else posted this link awhile ago, but it needs a re -post here:

I've reproduced the salient part below:
As I wrote in the notes above, Bengt Gustafsson was one of Edmonton's priority selections (the Oilers were the only team to use all of their available priority selections; the other teams only picked one skater each), however he was ultimately transferred to the Capitals. At issue was a directive the NHL gave the WHA during the merger negotiations: the WHA clubs were to cease all contract negotiations with players effective December 31, 1978 in order to prevent them from stocking up on players in anticipation of the merger. According to Oilers GM Larry Gordon the WHA didn't notify the member clubs' general managers of this directive until March of '79, after the merger was agreed upon. The Oilers signed Gustafsson after the December 31 cutoff date thus NHL President John Ziegler, after the Capitals presented this evidence to him, overruled the Oilers priority claim and transferred Gustafsson to the Capitals on Sept. 15, 1979. This was well after the expansion draft and the reclaim 'draft' so the Oilers had lost Gustafsson*and*the opportunity to reclaim someone else in his place.
Gustafsson was the only player whose rights were caught in this legal loophole. Goalie Hannu Kamppuri was signed by the Oilers in March of '79, and nobody had a problem with that...
OK, so the NHL issued a "Stop Signing Players" directive to the WHA, effective December 31, 1978. We know that the Oilers GM, Larry Gordon, claims that he and other WHA GMs never received this directive until months later. Yet, only the Oilers signed players after this "I know nuffing about day deadline." Gustafsson ' s signing was not recognized and he was awarded to the Caps. Kampurri's signing was ignored. Gretzky's signing resulted in a minor slap.
But we are left with one compelling question: if Gordon is correct and the "stop signing" directive never made it down the food chain, why didn't any other WHA club sign even one player after December 31st, 1978? Further, at that time many player agents, including Badali, represented clients in both leagues and surely would have known about the signing prohibition.
I can't be the only one to be thinking it walks like a duck . . .
