d," the partners
serving consecutively. While a side remains "in," service is made
alternately from each half court into the half court diagonally opposite,
the change of half courts taking place whenever an ace is scored. If, in
play, the shuttle strikes the net but still goes over, the stroke is good;
but if this happens in service and the service is otherwise good, it is a
"let," _i.e._ the stroke does not count, and the server must serve again,
even if the shuttle has been struck by the player served to, in which case
it is assumed that the shuttle would have fallen into the proper half
court. It is a "let," too, if the server, in attempting to serve, misses
the shuttle altogether. It is a good stroke, in service or in play, if the
shuttle falls on a line, or, in play, if it is followed over the net with
the striker's racket, or passes outside either of the net posts and then
drops inside any of the boundary lines of the opposite court. _Mutatis
mutandis_, the above remarks apply to the two-handed game, the main points
of difference being that, in the two-handed game, both sides change half
courts after each ace is scored and the same player takes consecutive
serves, whereas in the double game only the serving side changes half
courts at an added ace and a player may not take two consecutive serves in
the same game.

It is a "fault" (a) if the service is overhand, _i.e._ if the shuttle when
struck is higher than the server's waist; (b) if, in serving, the shuttle
does not fall into the half court diagonally opposite that from which
service is made; (c) if, before the shuttle is struck by the server, both
feet of the server and of the player served to are not inside their
respective half courts, a foot _on_ a line being deemed out of court; (d)
if, in play, the shuttle falls outside the court, or, in service or play,
passes through or under the net, or hangs in the net, or touches the roof
or side walls of the hall or the person or dress of any player; (e) if the
shuttle "in play" is hit before it reaches the striker's side; (f) if, when
the shuttle is "in play," a player touches the net or its supports with his
racket, person or dress; (g) if the shuttle is struck twice successively by
the same player, or if it is struck by a player and his partner
successively, or if it is not distinctly hit, _i.e._ if it is merely caught
on the racket and spooned over the net; (h) if a player wilfully obstructs
his opponent.
