=Section 3.=--Any company, association or corporation organized under the laws of this or any other State or nation, of which a majority of the members are aliens other than those specified in section one of this act, or in which a majority of the issued capital stock is owned by such aliens, may acquire, possess, enjoy, and convey real property, or any interest therein, in this State, in the manner and to the extent and for the purposes prescribed by any treaty now existing between the Government of the United States and the nation or country of which such members or stockholders are citizens or subjects, and not otherwise. Hereafter all aliens other than those specified in section one hereof may become members of or acquire shares of stock in any company, association or corporation that is or may be authorized to acquire, possess, enjoy or convey agricultural land, in the manner and to the extent and for the purposes prescribed by any treaty now existing between the Government of the United States and the nation or country of which such alien is a citizen or subject, and not otherwise. =Section 4.=--Hereafter no alien mentioned in section two hereof and no company, association or corporation mentioned in section three hereof, may be appointed guardian of that portion of the estate of a minor which consists of property which such alien or such company, association or corporation is inhibited from acquiring, possessing, enjoying or transferring by reason of the provisions of this act. The public administrator of the proper county, or any other competent person or corporation, may be appointed guardian of the estate of a minor citizen whose parents are ineligible to appointment under the provisions of this section. On such notice to the guardian as the court may require, the superior court may remove the guardian of such an estate whenever it appears to the satisfaction of the court: (_a_) That the guardian has failed to file the report required by the provisions of section five hereof; or (_b_) That the property of the ward has not been or is not being administered with due regard to the primary interest of the ward; or (_c_) That facts exist which would make the guardian ineligible to appointment in the first instance; or (_d_) That facts establishing any other legal ground for removal exist. =Section 5.=--(_a_) The term "trustee" as used in this section means any person, company, association or corporation that as guardian, trustee, attorney-in-fact or agent, or in any other capacity has the title, custody or control of property, or some interest therein, belonging to an alien mentioned in section two hereof, or to the minor child of such an alien, if the property is of such a character that such alien is inhibited from acquiring, possessing, enjoying or transferring it.
