Why The Service Let Survived Every Attempt To Remove It
Replaying a serve that clips the net is an oddity no other stroke gets, and the repeated attempts to abolish it reveal what the rule is quietly protecting.

A serve that clips the net and lands in is replayed, a privilege no other stroke receives. Attempts to abolish the rule keep failing, and the reasons are more interesting than tradition.
Why the let exists in the first place
The serve is the only stroke where a player is required to clear an obstacle with no opponent's shot to react to, and the net edge is a boundary of chance rather than skill.
A ball clipping the tape behaves unpredictably, losing speed and changing angle in ways no returner can anticipate and no server intended.
The let treats that as an accident of the equipment rather than an outcome of play, and replays the point to remove the randomness.
The case for playing lets
Removing the let would speed matches and eliminate disputes about whether contact occurred, which historically required a line judge with a hand on the net.
It would also remove a rule that occasionally rewards a server twice, since a second-serve let grants a fresh second serve rather than costing anything.
Formats aimed at shorter matches have adopted the change, and players adapt within a few games. The practical objections are smaller than the resistance suggests.
What the rule is actually protecting
The deeper argument is about the second serve. Without the let, a net cord on a second serve produces an unreturnable point through pure luck at the highest-pressure moment.
In a sport where a single break decides a set, concentrating chance at that point is a larger distortion than the time saved by removing replays.
The let therefore functions as a variance reducer at exactly the place the scoring structure is most sensitive, which is why abolition proposals keep stalling.
How detection changed the debate
Electronic sensors on the net replaced the human judge, removing the error and dispute that formed a large part of the practical case for abolition.
Once detection became reliable, the argument shifted from enforcement difficulty to philosophy, which is much harder ground for reformers.
A rule that is cheap to enforce and rarely misapplied has little pressure against it, and that is roughly where the service let now sits.
The wider category of lets
The service let is one instance of a broader principle in the laws, which is that play interrupted by something outside the contest should be replayed rather than awarded.
Balls rolling onto court, spectator interference and equipment failure are handled the same way, and the umpire's discretion to call a let covers unforeseen cases.
Seen in that context the service let is not an anomaly at all. It is the most frequent application of a general rule about not resolving points by accident.
