PART III Date of Development and Recrudescence

7 Development of disease

7. Where on a claim for benefit under section 54 of the Act in respect of a prescribed disease, an insured person is found to be or to have been suffering from the disease, or to have died as the result thereof, the disease shall, for the purpose of such claim, be treated as having developed on a date (hereafter referred to as "the date of development") determined in accordance with the provisions of articles 8 and 9.

8 Date of development

8. (1) For the purposes of the first claim in respect of a prescribed disease suffered by an insured person, the date of development shall be determined in accordance with the following provisions of this article, and, save as provided in article 9, that date shall be treated as the date of development for the purposes of any subsequent claim in respect of the same disease suffered by the same person;

provided that where, on the consideration of a claim, no award of benefit is made, any date of development determined for the purposes of that claim shall be disregarded for the purposes of any subsequent claim.

(2) Where a claim for the purposes of which the date of development is to be determined is—

(a) a claim for injury benefit, the date of development shall be either the first day on or after the 1st day of May, 1967 on which the claimant was incapable of work as the result of the disease or, where applicable, the date as from which benefit could be paid on that claim, or

(b) a claim for disablement benefit, the date of development shall be either the day on or after the 1st day of May, 1967 on which the claimant first suffered from the relevant loss of faculty or, where applicable, the date as from which benefit could be paid on that claim, or

9 Recrudescence

9. (1) Where an insured person has been awarded benefit under section 54 of the Act in respect of a prescribed disease other than pneumoconiosis, byssinosis, occupational asthma or occupational deafness and has recovered wholly or partially and thereafter suffers a further attack of the same disease, or dies as a result of such attack, then—

(a) Where the further attack of the disease commences or the death occurs during an injury benefit period or during a period taken into account by an assessment of disablement relating to such a previous award (either of which periods is hereinafter referred to as a "relevant period") it shall be treated as a recrudescence of the attack to which the relevant period relates except where, having regard to the particular circumstances relating to the further attack it is found that the disease was contracted or received afresh, in which case it shall be then so treated.

(b) Where the further attack of the disease commences or the death occurs on a date outside a relevant period, it shall be treated as having been contracted or received afresh.

(c) For the purposes of this sub-article, the date on which the further attack of the disease commenced shall be the date deemed to be the date of development under the provisions of article 8 applied as though no previous claim had been made in respect of the disease.

(2) Where, under the provisions of this article, a disease is treated as having been contracted afresh, the provisions of article 8 shall be applied as though no previous claim had been made in respect of that disease and the date of development shall be determined accordingly.

PART IV Modification of provisions of the Act and of Regulations

11 Definition

11.

(a) as having developed on a date other than the date which, under the said provisions, is treated as the date of development for the purposes of the claim under consideration; or

(b) as a recrudescence of a disease for which compensation has been paid or awarded under the Workmen's Compensation Acts.

12 Modifications of provisions of the Act

12. (1) The provisions of the Act shall, in relation to prescribed diseases, be subject to the following provisions of this Part of these Regulations.

(2) References in the Act to accidents against which a person was insured under the Act shall be construed as references to prescribed diseases against which he was so insured.

(4) References in section 56 of the Act to the time of the relevant accident shall be construed as references to the latest date, not later than the date of development, on which the person was employed in the employment to the nature of which the relevant disease is due.

13 Application of Claims and Payments Regulations and Occupational Injuries Regulations and the constructions of references in these Regulations

13. (1) Save in so far as they are expressly varied or excluded by, or are inconsistent with, the provisions of this Part of these Regulations, the Claims and Payments Regulations and the Occupational Injuries Regulations shall apply in relation to prescribed diseases as they apply in relation to accidents.

No. 19 of 1978 ) relating to persons employed in the exploration or exploitation of certain designated areas of the continental shelf, for the purpose of determining whether a prescribed disease is, or, under the provisions of Part II of these Regulations is presumed to be, due to the nature of the person's insurable (occupational injuries) employment, that person shall be regarded as not being or as not having been in insurable (occupational injuries) employment during any period for which he is or was outside the State, and accordingly occupational injuries benefit shall not be payable in respect of a prescribed disease which is due to the nature of employment in an occupation in which the insured person has only been engaged outside the State.

15 Injury benefit

15. (1) Subsection (3) of section 42 of the Act (which subsection provides that in determining whether the insured person is incapable of work on the day of the accident, any part of that day before the happening of the accident shall be disregarded) shall not apply.

16 Disablement benefit not preceded by injury benefit

16. Where an insured person, not having been entitled to injury benefit in respect of a relevant disease, claims disablement benefit in respect of that disease, and under the provisions of Part III of these Regulations, a date of development is determined for the purposes of that claim, the following provisions shall apply:

(a) subsection (2) of section 43 of the Act (which subsection relates to the period for which disablement benefit is not available) shall not apply and the claim shall be treated as if there had been no injury benefit period;

(b) subsection (5) of section 43 of the Act (which subsection relates to the period to be taken into account by an assessment of the extent of the claimant's disablement) shall have effect as if for references therein to the end of the injury benefit period there were substituted references to the date of development.

17 Assessment of extent disablement

17. For the purposes of paragraph (b) of subsection (3) of section 43 of the Act (which subsection relates to the disabilities to be taken into account in assessing the extent of the claimant's disablement) an injury or disease other than the relevant disease shall be treated as having been received or contracted before the relevant disease if it was received or contracted on or before the date of development, and as having been received or contracted after the relevant disease if it was received or contracted after that date.

18. Article 11 of the Social Welfare (Claims and Payments) (Amendment) Regulations, 1967 ( S.I. No. 85 of 1967 ) (which relates to the giving of notice of accidents in respect of which benefit may be payable) shall not apply in relation to prescribed diseases.
