“…Such audit standards and guidance statements are thought by some to represent practice in auditors' interest instead of providing a rigid standard of acceptable performance (Booth & Cocks, 1989). In view of this, Humphrey et al (1992) argued that the promulgation of audit standards and guidance statements gives "an appearance of standardisation and a rationalistic basis to audit expertise" although they note that details about standard promulgations are insufficient to gauge the nature of audit expertise and audit performance (Humphrey et al, 1992, p. 148). Thus, organisational influence on audit standards and guidance statements is questionable, and made further so by the standard or statements' use of subjective terms such as "reasonable, materiality, adequacy, relevance, reliability, sufficiency and judgement" (Humphrey et al, 1992, p. 48).…”
