දමලා ගහනවා නම් අයින් කරලම දාන්න ඕනේ.
ගොඩක් සුද්දොත් මේක කමෙන්ට් කරනවා.
ඇයි එච්චර Power එකක්. විරෝදයක් එන නිසාද

The International Cricket Council (ICC) didn’t change the rules
just for Muttiah Muralitharan but his case
triggered a major rethink of the bowling laws.
Here’s the real story in simple terms:
1. The original problem (the “chucking” rule)
In cricket, a bowler must not “throw” the ball.
Originally:
* Spinners (like Murali) → only
5° arm straightening allowed
* Medium pacers → 7.5°
* Fast bowlers → 10° ([The Guardian][1])
Murali’s bowling action—especially his
doosra looked unusual, so umpires and players often accused him of chucking.
2. Scientific testing changed everything
The ICC conducted detailed biomechanical studies and found something surprising:
* Almost all bowlers straighten their arm more than the old limits
* Even “normal” bowlers exceeded 5° regularly ([Wikipedia][2])
In fact:
* Natural elbow movement can be
3°–20°
* Umpires
cannot visually detect small differences reliably
3. Murali’s case exposed the flaw
Murali’s doosra was measured at around:
* ~14° initially (above the old 5° limit) ([Wikipedia][2])
So technically, under old rules:

He would be illegal

But so would MANY other bowlers
This made the ICC realise:
* The rule itself was unrealistic and unfair
4. The rule change (2004–2005)
The ICC introduced a
new universal rule:
All bowlers allowed up to
15° elbow straightening ([ABC News][3])
Why 15°?
* That’s roughly the point where bending becomes
visible to the human eye
* It matches
natural human biomechanics
5. Was the rule changed just for Murali?
No but he was the catalyst
* His case forced testing and debate
* Research showed the
old law was broken by almost everyone
* So ICC updated the law for
fairness and science
Some critics say it “helped Murali,” but ICC’s position was:
> If we applied the old rule strictly,
almost no bowler would be legal ([Wikipedia][2])
