Section 101.45 - Mutually exclusive applications(a) The Commission will consider applications to be mutually exclusive if their conflicts are such that the grant of one application would effectively preclude by reason of harmful electrical interference, or other practical reason, the grant of one or more of the other applications. The Commission will presume "harmful electrical interference" exists when the levels of § 101.105 are exceeded, or when there is a material impairment to service rendered to the public despite full cooperation in good faith by all applicants or parties to achieve reasonable technical adjustments which would avoid electrical conflict.(b) A common carrier application, except in the Local Multipoint Distribution Service and in the 24 GHz Service, will be entitled to comparative consideration with one or more conflicting applications only if:(1) The application is mutually exclusive with the other application; and(2) The application is received by the Commission in a condition acceptable for filing by whichever "cut-off" date is earlier:(i) Sixty (60) days after the date of the public notice listing the first of the conflicting applications as accepted for filing; or(ii) One (1) business day preceding the day on which the Commission takes final action on the previously filed application (should the Commission act upon such application in the interval between thirty (30) and sixty (60) days after the date of its public notice).(c) Whenever three or more applications are mutually exclusive, but not uniformly so, the earliest filed application established the date prescribed in paragraph (b)(2) of this section, regardless of whether or not subsequently filed applications are directly mutually exclusive with the first filed application. (For example, applications A, B, and C are filed in that order. A and B are directly mutually exclusive, B and C are directly mutually exclusive. In order to be considered comparatively with B, C must be filed within the "cut-off" period established by A even though C is not directly mutually exclusive with A.)(d) Private operational fixed point-to-point microwave applications for authorization under this part will be entitled to comparative consideration with one or more conflicting applications in accordance with the provisions of § 1.227(b)(4) of this chapter.(e) An application otherwise mutually exclusive with one or more previously filed applications, but filed after the appropriate date prescribed in paragraphs (b) or (d) of this section, will be returned without prejudice and will be eligible for refiling only after final action is taken by the Commission with respect to the previously filed application (or applications).(f) For purposes of this section, any application (whether mutually exclusive or not) will be considered to be a newly filed application if it is amended by a major amendment (as defined by § 1.929 of this chapter), except under any of the following circumstances:(1) The application has been designated for comparative hearing, or for comparative evaluation (pursuant to § 101.51 of this part), and the Commission or the presiding officer accepts the amendment pursuant to § 1.927 of this chapter;(2) The amendment resolves frequency conflicts with authorized stations or other pending applications which would otherwise require resolution by hearing or by comparative evaluation pursuant to § 101.51 provided that the amendment does not create new or additional frequency conflicts;(3) The amendment reflects only a change in ownership or control found by the Commission to be in the public interest, and for which a requested exemption from the "cut-off" requirements of this section is granted;(4) The amendment reflects only a change in ownership or control which results from an agreement under § 1.935 of this chapter whereby two or more applicants entitled to comparative consideration of their applications join in one (or more) of the existing applications and request dismissal of their other application (or applications) to avoid the delay and cost of comparative consideration;(5) The amendment corrects typographical, transcription, or similar clerical errors which are clearly demonstrated to be mistakes by reference to other parts of the application, and whose discovery does not create new or increased frequency conflicts; or(6) The amendment does not create new or increased frequency conflicts, and is demonstrably necessitated by events which the applicant could not have reasonably foreseen at the time of filing, such as, for example: (i) The loss of a transmitter or receiver site by condemnation, natural causes, or loss of lease or option;(ii) Obstruction of a proposed transmission path caused by the erection of a new building or other structure; or(iii) The discontinuance or substantial technological obsolescence of specified equipment, whenever the application has been pending before the Commission for two or more years from the date of its filing.(g) Applicants for the 932.5-935/941.5-944 MHz bands shall select a frequency pair. Applicants for these bands may select an unpaired frequency only upon a showing that spectrum efficiency will not be impaired and that unpaired spectrum is not available in other bands. During the initial filing window, frequency coordination is not required, except that an application for a frequency in the 942-944 MHz band must be coordinated to ensure that it does not affect an existing broadcast auxiliary service licensee. After the initial filing window, an applicant must submit evidence that frequency coordination has been performed with all licensees affected by the application. All frequency coordination must be performed in accordance with § 101.103 . In the event of mutually exclusive applications occurring during the initial filing window for the 932.5-935/941.5-944 MHz bands, applicants shall be given the opportunity to resolve these situations by applying for an alternative frequency pair, if one is available. To the extent that there are no other available frequencies or to the extent that mutually exclusive applications remain after this process is concluded, lotteries shall be conducted for each frequency pair among all remaining mutually exclusive applications, assuming appropriate coordination with existing broadcast auxiliary stations can be concluded, where necessary. In the event of mutually exclusive applications being received for these bands on the same day after the initial filing window has closed and a subsequent filing window opened, lotteries shall be conducted for each frequency pair among all mutually exclusive applications.61 FR 26677, May 28, 1996, as amended at 62 FR 23164, Apr. 29, 1997; 62 FR 24582, May 6, 1997; 63 FR 6103, Feb. 6, 1998; 63 FR 68982, Dec. 14, 1998; 65 FR 59357 , Oct. 5, 2000
