Well somebody should probably notice that national symbols changed since the split of Czechoslovakia as this one lion was never seen on Czech republic jerseys (23 years already)....If the source is correct there is no one else to blame....
It probably comes down to interpretation of the law. The national football team uses a single lion both in their logo and on their kits, yet the shield itself is of their own design. I haven't looked into what the official version's shield looks like, but the one the NHL chose is different from the one used back in the Czechoslovakia days, so perhaps the interpretation is that a single lion is OK as long as it's not in the official government legislated shield.
