We know what the criteria are for taking a QTI (well, almost ...)
It would be nice if the laws filled in the blanks for a regular lineout in the same detailed fashion.
isn't that exactly what 19.8 does?
I think no line out can take place until all of 19.8 is satisfied, and if the non-throwing team attempt to delay then the sanction is specified -- it's a FK (NOT that the trhowing team can take it anyway)
[LAWS]19.8 Forming a lineout
The lineout
(a) Minimum. At least two players from each team must form a lineout.
Sanction: Free Kick on the 15-metre line
(b) Maximum. The team throwing in the ball decides the maximum number of players in the lineout.
(c)
The opposing team may have fewer lineout players but they must not have more.
Sanction: Free Kick on the 15-metre line
(d)
When the ball is in touch, every player who approaches the line of touch is presumed to do so to form a lineout. Players who approach the line of touch must do so without delay. Players of either team must not leave the lineout once they have taken up a position in the lineout until the lineout has ended.
Sanction: Free Kick on the 15-metre line
(e)
If the team throwing in the ball put fewer than the usual number of players in the lineout, their opponents must be given a reasonable time to move enough players out of the lineout to satisfy this Law.
Sanction: Free Kick on the 15-metre line
(f)
These players must leave the lineout without delay. They must move to the offside line, 10 metres behind the line of touch. If the lineout ends before they reach this line, they may rejoin play.
Sanction: Free Kick on the 15-metre line
(g) Failure to form a lineout. A team must not voluntarily fail to form a lineout.
Sanction: Free Kick on the 15-metre line
(h) Where the lineout players must stand. The front of the lineout is not less than 5 metres from the touchline. The back of the lineout is not more than 15 metres from the touchline. All lineout players must stand between these two points.
Sanction: Free Kick on the 15-metre line
(i) Where the receiver must stand. If a team uses a receiver, then that player, must be positioned at least 2m back from team mates in the lineout, and between the 5m and 15m lines, until the lineout begins.
Once the lineout has commenced, the receiver may move into the lineout and may perform all actions available to players in the lineout and is liable to related sanctions.
Sanction: Free kick on the 15 metre line along the line of touch
(j) Player between touch and 5 metres. The team not throwing in must have a player standing between the touchline and the 5-metre line on that team’s side of the line of touch when the lineout is formed. That player must stand 2 metres from the line of touch and 2 metres from the 5-metre line.
Sanction: Free Kick on the 15-metre line
(k)
Participating players in a lineout may change places before the ball is thrown.
(l) Two single straight lines. The lineout players of both teams form two single parallel lines each at right angles to the touchline.
Sanction: Free Kick on the 15-metre line
(m)
Opposing players forming a lineout must keep a clear space between their inside shoulders. This space is determined when players are in an upright stance.
Sanction: Free Kick on the 15-metre line
Metre gap. Each line of players must be half a metre on their side of the line of touch.
Sanction: Free Kick on the 15-metre line
(o)
The line of touch must not be within 5 metres of the goal line.
(p)
After the lineout has formed, but before the ball has been thrown in, a player must not hold, push, charge into, or obstruct an opponent.
Sanction: Penalty [/LAWS]
