Where must all pleadings and motions be filed in relation to the Board?

All pleadings and motions must be filed at the Board office because this centralizes the process within the appropriate regulatory authority that oversees such matters. The Board is responsible for maintaining official records, ensuring that all submissions are processed correctly according to their governing laws and regulations. This also allows for consistent management and access to legal documents pertinent to the Board's operations.

Filing at the Board office ensures that the materials are received by the correct personnel who can properly review, respond, and manage the proceedings, maintaining the integrity of the legal process in relation to the Board’s functions. This location is specifically designated for such filings, providing the necessary infrastructure and authority to handle the legal aspects effectively.

In contrast, filing at the respondent's office, a designated court, or any public library would not meet the requirements set forth by the regulatory procedures; each of these alternatives lacks the official capacity and administrative framework necessary for such legal documentation.
