His opponent starts Black clock without making his move. He claimed that based on FIDE rules, when the Black player is late, White could delay making his first move on the board until the opponent actually arrives, while still being allowed to start Black's clock.
I don't think there's any such rule, although there might have been in the past, or local rules to that effect. The only specified action is where neither player is present.

Before the start of the game the arbiter decides where the chess clock is placed.

At the time determined for the start of the game the clock of the player who has the white pieces is started.

a.Any player who arrives at the chessboard after the start of the session shall lose the game. Thus the default time is 0 minutes. The rules of a competition may specify otherwise.
b.If the rules of a competition specify a different default time, the following shall apply. If neither player is present initially, the player who has the white pieces shall lose all the time that elapses until he arrives, unless the rules of the competition specify or the arbiter decides otherwise.
There is however this material about adjournments from

If, at the agreed resumption time:
a. the player having to reply to the sealed move is present, the envelope is opened, the sealed move made on the chessboard and his clock started.
b.the player having to reply to the sealed move is not present, his clock shall be started. On his arrival, he may stop his clock and summon the arbiter. The envelope is then opened and the sealed move made on the chessboard. His clock is then restarted.
c.the player who sealed the move is not present, his opponent has the right to record his reply on the scoresheet, seal his scoresheet in a fresh envelope, stop his clock and start the absent player’s clock instead of making his reply in the normal manner. If so, the envelope shall be handed to the arbiter for safe-keeping and opened on the absent player’s arrival.
At the back of my mind are precedents where arbiters, when deemed present, have allowed the player with the white pieces to seal the first move in the absence of his opponent. On a slightly different tack, it would be my impression that a player should be allowed to take back their first move and substitute an alternative if a reserve replaces the original player in a team match. There again that's probably just convention or local rules.
