New ICC rules to take effect on Oct 1 The following amendments were approved by the ICC executive board at its meeting in London in May

The bowler is permitted, before releasing the ball and
provided he has not completed his usual delivery swing, to
attempt to run out the non-striker. Whether the attempt is
successful or not, the ball shall not count. If the bowler fails
in an attempt to run out the non-striker, the umpire shall
call and signal dead ball as soon as possible.

A runner for a batsman
shall not be permitted in
any of the formats. Unless
nine wickets are down, the
injured or ill batsman has
the option of retiring hurt
and returning to bat at a
later stage should the need
or opportunity arise.

The total number of Powerplay
overs remain at 20 per innings
with the first block of 10
mandatory at the
commencement of the innings.
However the second and third
Powerplay overs may not be
taken earlier than the 16th over
nor be completed later than
the 40th over.

Two balls, instead of
one, will be used in
each innings of an
ODI match.

Calculation of the period for
which an injured or ill player
who has been absent from the
field shall not be permitted to
bowl or bat i.e. penalty time
(Tests, ODIs and T20Is)

On appeal from the fielding
team, if the umpire feels
that a batsman, whilst
running between the
wickets, has significantly
changed his direction
without probable cause
thereby obstructing a
fielder’s attempt to run him
out, the batsman should be
given out ‘obstructing the
field’. It shall not be
relevant whether a run
out would have been
affected or not. This is
applicable in all three
formats.
In making a decision in this
regard, the on-field umpires
are entitled to consult the
third umpire in deciding
whether the obstruction
was wilful or not with the
final decision being made
and conveyed by the
relevant on-field umpire.

In another change in Tests,
the playing conditions now
provide that if nine wickets
are down at the time of the
scheduled lunch interval,
the interval shall be delayed
by a maximum of 30
minutes as it is with tea
interval.
In Tests, the umpires may
now decide to play 15
minutes (a minimum of four
overs) extra time at the
scheduled lunch or tea
interval of any day if
requested by either captain
if, in the umpires’ opinion, it
would bring about a definite
result in that session. If the
umpires do not believe a
result can be achieved no
extra time shall be allowed.

The minimum interval for
an uninterrupted ODI
match has been
increased from 20
minutes to 30 minutes.
