1.   Ní bheidh an phróiseáil dleathach ach amháin má tá feidhm, agus a mhéid atá feidhm, le ceann díobh seo a leanas ar a laghad:

(a)	tá toiliú tugtha ag an ábhar sonraí a shonraí pearsanta nó a sonraí pearsanta a phróiseáil chun ceann amháin nó níos mó de chríocha sonracha;

(b)	is gá an phróiseáil a dhéanamh chun conradh ar páirtí ann an t-ábhar sonraí a chomhlíonadh nó chun bearta a dhéanamh arna iarraidh sin ag an ábhar sonraí sula ndéanfaidh sé nó sí conradh;

(c)	is gá an phróiseáil a dhéanamh chun oibleagáid dhlíthiúil a bhfuil an rialaitheoir faoina réir a chomhlíonadh;

(d)	is gá an phróiseáil a dhéanamh chun leasanna ríthábhachtacha an ábhair sonraí nó duine nádúrtha eile a chosaint;

(e)	is gá an phróiseáil a dhéanamh chun cúram a chur i gcrích a dhéantar ar mhaithe le leas an phobail nó i bhfeidhmiú údaráis oifigiúil atá dílsithe don rialaitheoir;

(f)

is gá an phróiseáil a dhéanamh chun críocha na leasanna dlisteanacha atá á saothrú ag an rialaitheoir nó ag tríú páirtí, seachas i gcás ina mbeidh sáraíocht ag na leasanna sin ar leasanna nó ar chearta bunúsacha agus ar shaoirsí bunúsacha an ábhair sonraí, lena gceanglaítear go ndéanfar sonraí pearsanta a chosaint, go háirithe más leanbh é an t-ábhar sonraí.

Ní bheidh feidhm ag pointe (f) den chéad fhomhír maidir le próiseáil a dhéanann údaráis phoiblí i gcomhlíonadh a gcúraimí.

2.   Féadfaidh na Ballstáit forálacha níos sonraí a choimeád ar bun nó a thabhairt isteach chun cur i bhfeidhm rialacha an Rialacháin seo a oiriúnú i ndáil le próiseáil chun pointe (c) agus pointe (e) de mhír 1 a chomhlíonadh trí chinneadh níos cruinne a dhéanamh maidir le ceanglais shonracha don phróiseáil agus do na bearta eile chun próiseáil dhleathach agus chothrom a áirithiú lena n-áirítear le haghaidh cásanna sonracha próiseála eile dá bhforáiltear i gCaibidil IX.

3.   Déanfar an bunús don phróiseáil dá dtagraítear i bpointe (c) agus i bpointe (e) de mhír 1 a leagan síos leis méid seo a leanas:

(a)	dlí an Aontais; nó

(b)	dlí Ballstáit a bhfuil an rialaitheoir faoina réir.

Cinnfear críoch na próiseála sa bhunús dlí sin nó, maidir leis an bpróiseáil dá dtagraítear i bpointe (e) de mhír 1, beidh ga léi le haghaidh cúram chur i gcrích a dhéantar ar mhaithe le leas an phobail nó i bhfeidhmiú údaráis oifigiúil atá dílsithe don rialaitheoir. Féadfaidh forálacha sonracha a bheith sa bhunús dlí sin chun cur i bhfeidhm rialacha an Rialacháin seo a oiriúnú, lena n-áirítear na coinníollacha ginearálta lena rialaítear dlíthiúlacht na próiseála sonraí ag an rialaitheoir; an cineálacha sonraí atá faoi réir a bpróiseála; na hábhair sonraí lena mbaineann; na heintitis a bhféadfar na sonraí pearsanta a nochtadh dóibh agus na críocha ar chucu a bhféadfar iad a nochtadh dóibh; an teorannú de réir cuspóra; tréimhsí stórála; agus oibríochtaí próiseála agus nósanna imeachta próiseála, lena n-áirítear bearta chun próiseáil dhleathach agus chothrom a áirithiú, amhail iad sin do staideanna sonracha próiseála eile dá bhforáiltear i gCaibidil IX. Comhlíonfaidh dlí an Aontais nó dlí Ballstáit cuspóir a bhaineann le leas an phobail agus beidh sé i gcomhréir leis an aidhm dhleathach atá á saothrú.

4.   I gcás nach bhfuil an phróiseáil chun críche eile seachas an chríoch ar chuici a bailíodh na sonraí pearsanta bunaithe ar thoiliú an ábhair sonraí nó ar dhlí de chuid an Aontais nó ar dhlí Ballstáit atá mar bheart riachtanach agus comhréireach i sochaí dhaonlathach chun na cuspóirí dá dtagraítear in Airteagal 23(1) a choimirciú, déanfaidh an rialaitheoir, d'fhonn fáil amach an bhfuil críoch na próiseála ag luí leis na críocha sin ar chucu a bailíodh na sonraí pearsanta ar an gcéad dul síos, na nithe seo a leanas, inter alia, a chur san áireamh:

(a)	aon nasc idir na críocha ar bailíodh na sonraí pearsanta chucu agus na críocha atá leis an tuilleadh próiseála atá beartaithe;

(b)	an comhthéacs inar bailíodh na sonraí pearsanta, go háirithe maidir leis an ngaol idir na hábhair sonraí agus an rialaitheoir;

(c)	cineál na sonraí pearsanta, go háirithe an ndéantar catagóirí speisialta sonraí pearsanta a phróiseáil, de bhun Airteagal 9, nó an ndéantar sonraí pearsanta a bhaineann le ciontuithe coiriúla agus coireanna a phróiseáil, de bhun Airteagal 10;

(d)	na hiarmhairtí a d'fhéadfadh a bheith ann do na hábhair sonraí ag an tuilleadh próiseála atá beartaithe;

(e)	an bhfuil coimircí iomchuí ann, ar a bhféadfar a áirithiú criptiú a dhéanamh nó ainm bréige a chur i bhfeidhm.

2.   Member States may maintain or introduce more specific provisions to adapt the application of the rules of this Regulation with regard to processing for compliance with points (c) and (e) of paragraph 1 by determining more precisely specific requirements for the processing and other measures to ensure lawful and fair processing including for other specific processing situations as provided for in Chapter IX.
