IMPs. Swiss Teams. Table Result 5Sx=
This was a potential appeal from a London Swiss Teams, which North decided to withdraw as his team was not in contention. West is a top international. East is much less experienced and not expert. The contract made, and the TD ruled that West's 5S was either the only LA or not demonstrably suggested by the speed of the double (he did not specify which). East's double might not be everyone's choice (!) but do you agree with the TD ruling? There was no agreement on the meaning of double and presumably was intended as penalties.
Some views on LAs can be discerned from the High Level Decision thread in Intermediate and Advanced Bridge Discussions.
