Los Angeles County Superior Court's 2024 search procedure change removed birth-date criteria from criminal record searches, making background checks unreliable for 10 million residents

On February 23, 2024, the Superior Court of Los Angeles County stopped using birth month and year as search criteria for criminal background checks, meaning background screening companies can no longer reliably match criminal records to specific individuals in the most populous county in the United States (10.04 million residents). This causes either false positives (matching the wrong person's criminal record to a candidate) or false negatives (missing actual criminal records). Why it matters: employers conducting background checks on LA County candidates receive less accurate results, so they either rescind offers based on mismatched records or miss genuine criminal history, so candidates with common names face disproportionate delays and false hits, so employers in safety-sensitive industries (healthcare, education, finance) face increased negligent hiring liability, so some employers avoid hiring LA County residents altogether to sidestep the compliance risk. The structural root cause is that county courts control their own records systems and search procedures with no standardization mandate, and when courts modernize or change procedures for their own administrative reasons (privacy, system upgrades), they have no obligation to consider the downstream impact on employment background screening workflows.
