Ground 3: Contrary to section 14(6) of the Act,
(a) O'Brien failed to reject the payment claim dated 24th April 2009 on the basis that it amounted to a further payment claim in respect of the payment claims dated 26th September 2008, 24th October 2008, 28th November 2008 and 5th December 2008 and in essence merely duplicated those respective payment claims; and
(b) it was not open to O'Brien to find in accordance with law or the Act, and he erred in so finding, that the payment claim dated 24th April 2009 was valid despite section 14(6) of the Act.
Ground 4: Alternatively to Ground 3 above, it was not open to O'Brien to find in accordance with law or the Act, and he erred in so finding, that section 14(7) of the Act applied to the payment claim dated 24th April 2009 or that PCJV was entitled to serve the said payment claim in circumstances where it did not claim for further work or additional sums alleged to be due.
Ground 5: Contrary to section 14(8) of the Act, O'Brien erred by failing to reject the payment claim dated 24th April 2009 on the basis that it amounted to more than one payment claim in respect of the reference dates 26th September 2008, 24th October 2008, 28th November 2008 and 5th December 2008.
Ground 6: Alternatively to Ground 5 above, it was not open to O'Brien to find in accordance with law or the Act, and he erred in so finding, that the payment claim dated 24th April 2009 was not made in respect of the reference dates 26th September 2008, 24th October 2008, 28th November 2008 and 5th December 2008.
Ground 7: Contrary to section 14(9) of the Act, it was not open at law for O'Brien to find, and O'Brien erred in finding, that PCJV was entitled to rely on section 14(9) of the Act in respect of the payment claim dated 24th April 2009 where that claim:
(a) Was in respect of exactly the same work and charges for the payment claims dated 26th September 2008, 24th October 2008, 28th November 2008 and 5th December 2008; and/or
(b) Was in respect of exactly the same reference dates 26th September, 2008, 24th October 2008, 28th November 2008 and 5th December 2008; and
(c) No claim was made by PCJV for any further work or sums or in respect of any later reference dates arising after or in addition to those said payment claims or reference dates.
