When an attorney's disregard for the client's interest is habitual, or is severe discipline imposed on an attorney who fails to render services?

When an attorney's disregard of his clients' interest is 'habitual' (Ridley v. State Bar (1972) 6 Cal.3d 551, 560--561, 99 Cal.Rptr. 873, 493 P.2d 105; Grove v. State Bar (1967) supra, 66 Cal.2d 680, 683--684, 58 Cal.Rptr. 564, 427 P.2d 164), or when failure to render services is combined with failure to communicate with the client and with misrepresentation, severe discipline has been imposed. (Alkow v. State Bar (1971) 3 Cal.3d 924, 936, 92 Cal.Rptr. 278, 479 P.2d 638; Rock v. State Bar (1962) 57 Cal.2d 639, 643--644, 21 Cal.Rptr. 572, 371, P.2d 308.)
