Final answer:
An applicant with certain criminal convictions can be denied a timeshare interest sales registration if deemed untrustworthy, which aligns with historic and modern practices of restricting rights for those with criminal backgrounds.
Step-by-step explanation:
An applicant who has been convicted of certain crimes, such as forgery, embezzlement, obtaining money under false pretenses, larceny, extortion, conspiracy to defraud, theft, or any felony or crime involving moral turpitude, may be refused a timeshare interest sales registration if the applicant is found to be untrustworthy. While the question provides a list of specific crimes, the key factor in refusing registration is not simply the conviction of these crimes, but rather the determination that the applicant is untrustworthy. This is consistent with historical and modern legal frameworks where those with criminal convictions are often restricted from certain rights and privileges, whether it be voting rights as per the Fourteenth Amendment or the denial of professional licenses, as a means of ensuring trust and integrity within certain professions or civic functions.
