During the validation process.
The successful miner will have validated transactions and in the case of a double spend where all conflicting transactions are still unconfirmed, the miner will have chosen one of them based on their own criteria such as fees, other associated unconfirmed transactions, and their fees. That is how a double spend is RESOLVED.
A double spend is PREVENTED when nodes validate blocks and ensure that there are no double spends present within the blockchain. If a double spend is detected, then the block is not appended to the user's blockchain and the double spend is prevented. This happens the same on all nodes across the network.
